The team led by Professor In Soo-Il in the Department of Energy Engineering at DGIST has developed a high-efficiency photocatalyst capable of converting carbon dioxide (CO₂), a major contributor to global warming, into the energy resource methane. The research team optimized the composition of nanoparticle co-catalysts and ruthenium doping to maximize the optical and electrical properties of the photocatalyst.

Simultaneously, they improved the methane conversion efficiency by enhancing CO₂ adsorption through hydroxy surface treatment. The research team expects this technology to be applicable to carbon capture and utilization, making it possible to control the steadily increasing concentration of atmospheric CO₂ while converting it into methane resources.

In 2022, the global CO₂ concentration surpassed 420ppm, the highest level in 4.1 million years. Unprecedented increases in atmospheric CO₂ concentrations have led to climate-related disasters worldwide, including 20 billion USD (approximately 25.4 trillion KRW) in economic losses due to droughts in Europe and record-breaking torrential rains on the Korean Peninsula.

To address this issue, the concentration of CO₂, the cause of climate disasters, should be reduced. The World Economic Forum has identified “solar compounds” capable of converting CO₂, a major contributor to global warming, into various fuels using solar energy as one of the top ten promising technologies of 2020.

Among solar compound technologies, photocatalysts that convert highly stable CO₂ into fuels such as methane using only sunlight and photocatalysts through gas-phase reactions are drawing attention as key technologies for the future chemical industry, with the aim to reduce atmospheric CO₂ and produce fuel simultaneously.

However, currently commercialized photocatalysts like P25 have limitations, such as a large bandgap that prevents the absorption of visible light and slow charge transfer. Several studies have attempted to solve these issues. However, challenges in achieving high-efficiency photocatalyst development have persisted due to inherent problems like low CO₂ adsorption and conversion efficiency in gas-phase reactions.

The research team at DGIST led by Professor In Soo-Il developed a high-efficiency photocatalyst by attaching silver nanoparticle co-catalysts to P25 made of titanium dioxide, and improving charge transfer performance with ruthenium doping. They also resolved the issue of a low CO₂ concentration on the catalyst surface during gas-phase reactions by forming hydroxy groups on the surface of the photocatalyst through hydrogen peroxide treatment.

The research team demonstrated that electrons accumulate in an intermediate state of the P25 band structure through ruthenium doping. These accumulated electrons are then transferred to the silver nanoparticle co-catalyst, converting CO₂ into methane.

The team also identified the optimal composition to efficiently produce methane from CO₂ by analyzing the silver nanoparticle co-catalyst and ruthenium doping. Furthermore, by measuring the amount of adsorbed CO₂, they proved that the photocatalyst surface adsorbed more acidic CO₂ when it was alkalized with hydrogen peroxide.

Professor In Soo-Il from DGIST stated, “The newly developed photocatalyst improves visible light absorption, CO₂ adsorption, and electron transfer capabilities simultaneously. It converts 135 times more methane with 95% selectivity compared to the currently commercialized P25 photocatalysts and maintains over 96% stability even after 24 hours of continuous operation. We will conduct follow-up research to improve the stability and selectivity of hydrocarbons for the practical application of this technology.”

The results of this research were published in Carbon Energy.

Pune, 19th September 2023: An eco-friendly idol making workshop was organised by Rtn Harsha Joshi, Literacy Director of Rotary Club of Pune Professionals, Amanora to encourage children to sculpt their own Ganpati Bappa idol.

Ahead of the Ganesh festival, RCP Professionals organised an eco-friendly idol making workshop on September 15th to encourage children to sculpt their own Ganpati Bappa idol made with ‘shadu mati’ (clay) at Jijabai School in Hadapsar.

Shadu clay idols dissolve faster than those made of regular clay. By using clay and natural materials, we can honour tradition while protecting the environment. It is environment-friendly and has a low carbon footprint. At the time of immersion, it can be immersed in a bucket of water at home wherein it returns into its clay form and can be reused for sculpting.
“This workshop was conducted for the kids of 1st grade to 4th grade. They are fast learners. They learnt how to sculpt their own eco-friendly Ganesh idol during the workshop,” said Rtn Harsha Joshi.

The idols will be delivered to the people through zonal offices of all the zones of MCD.

An awareness campaign for the use of eco-friendly Ganesha idols will be conducted by zonal offices.

Mayor Oberoi said that people will have to think how they can make Delhi clean and pollution-free.

“Today the whole country and the world are struggling with climate change. I hope that the people of Delhi will support us in this work of keeping Delhi clean,” she said.

Meanwhile, the mayor’s office said “fogging will be started by the MCD” in Delhi from Tuesday to check growth of mosquito larvae.

The mayor has given directions to start fogging, which will be done with more than 1,000 machines, on a large scale in all 250 wards immediately.

Oberoi said that MCD is working to check growth of mosquito larvae “at about 1.5 lakh places daily. Notices are being sent and challans are being issued when larvae breeding are found in houses”.

In view of the rains and waterlogging in Delhi, the mayor on Monday held a review meeting of the public health department at the Civic Centre for the prevention of mosquito-borne diseases.

She said that the MCD is taking all necessary steps on a “war-footing to prevent dengue, malaria, chikungunya and other mosquito-borne diseases and the situation is under control”.

Also, Oberoi, along with local councillors, embarked on a comprehensive inspection of two wards in Delhi as part of the ongoing ‘Ab Delhi Hogi Saaf’ mega cleanliness campaign.

The inspection covered ward no. 72 of Sadar Bazaar and ward no. 142 of Daryaganj.

Oberoi, who has been actively supervising the campaign alongside senior MCD officials, highlighted the “positive impact of G20” on the city’s developmental work.

Debina Bonnerjee and Gurmeet Choudhary are couple goals and fans love them for the bond they share. For a long time, they have been preoccupied with work and parental duties due to which they had to be away from an International vacation plan.
However, the long wait for them ended recently when they decided to plan a month-long holiday earlier that’s all set to end now as Ganpati festival approaches.
Just like every other year, this year too, the couple is extremely excited for Ganpati festival. What makes it even more special is that this is their first Ganpati festival after the birth of their little one, Divisha.
Debina and Gurmeet are two individuals who are socially aware and that’s why, they are all for a safer and greener environment. That’s exactly why they are specifically keen on celebrating Ganpati festival this time too in an eco-friendly manner.
Gurmeet and Debina reveal, “Every year, during the time of Visarjan, a lot of toxic colours and materials merge with the water bodies and that is extremely harmful and hazardous for nature as well as the water species. As responsible citizens and public figures, our responsibility is to just do the right thing, but also influence others to do the same so that the awareness spreads. Since the past few years, we have been celebrating Ganpati festival in an eco-friendly way and this year too, we will be doing the same. We also urge all our fans and citizens of this country to follow the same so that nature isn’t harmed at the cost of our celebrations. Like the past few years, we will be bringing an eco-friendly Ganesh ji idol that will be made of 100% clay and non-toxic colours. The idol that we will have will be made of clay, natural fibers, paper and other biodegradable materials. The idea is to ensure that it degrades inside water in a healthy way without causing any detrimental effect to the environment, especially the ones made of POP. We urge others as well to kindly follow this every year. If we respect nature, only then will nature respect us in the long run.”

Meow Wolf’s first ever in-house fashion show: Absolute Rubbish: A Trashion Show is just around the corner.

Absolute Rubbish was inspired by the collision of innovation and sustainability. As a B Corporation, Meow Wolf is held accountable to sustainable practices and standards, and many of the employees’ costumes and uniforms are made sustainably.

It’s why their first in-house fashion show focuses on sustainable fashion. Instead of buying new, the Trashion show promotes upcycling and recycling found and discarded items. 

At the Trashion Show, 20 designers will each show an avant-garde look. These looks will be created from items generally discarded – either upcycling secondhand textiles or recycling household items and other unconventional materials. 

In preparation for their show, mannequins popped around Denver modeling one-of-a-kind upcycled and recycled looks that will not be shown at the show itself but to generate excitement. 

Three mannequins were displayed at Stanley Marketplace in the week leading up to the show. Mannequins were designed by Brandi Shigley, founder of Fashion Denver, Meghan Anderson Doyle, founder of Doyle Costume Design, and Meow Wolf’s Wardrobe Coordinator, Kate Major.

Brandi Shigley-McMichael’s design at Stanley Marketplace was inspired by the unhoused community in her neighborhood. The mannequin is wearing a dress made mostly from blue plastic tarp, decorated with torn newspaper. The dress is elevated with gold hardware adornments, including gold rope and a necklace fashioned from thick spiraled piping. Styled with ruched upcycled pink fabric and a plastic mesh bag, Shigley-McMichael’s design takes discarded trash and makes it feminine couture. 

Shigley-McMichael is the founder of Fashion Denver who will show another unique design at Meow Wolf’s trashion show. Fashion Denver was established in 2004 in the effort to support Colorado designers through production of fashion markets, fashion shows, and business development. 

“Regarding my process, I love to work from piles. Materials come alive when they’re in piles on the ground, colors jump out at me and my creation comes to life,” Shigley-McMichael said. “My design process is just like it was when I was a kid — create from a mess of color.”

Meghan Anderson Doyle‘s design is a vintage-style dress constructed from brown paper bag material. The silhouette of the dress is reminiscent of 1950s style, with pleating around the waist, short fitted sleeves, and a modest v-neckline. Cinched at the waist with a paper belt and tastefully crinkled, Doyle’s paper dress shows masterful styling and expert construction: the sophisticated silhouette is countered by Doyle’s unconventional and understated choice of material.

Doyle is a freelance costume designer who specializes in design for live theatre. Beyond participating in the Trashion Show, Doyle is currently in her 17 season as a Costume Design Associate with the Denver Center for Performing Arts. 

“As a costume designer for live theatre, I love the collision of art and history and style that is fashion,” Doyle said.

Years ago, Doyle made a paper bag dress and loved the quirky take on vintage style juxtaposed with “the impermanence of fashion,” She said.

“I jumped at the opportunity to revisit that idea with a new design aesthetic and showcase it with exciting designers in an incredible space with Absolute Rubbish,” Doyle said. “Getting the chance to envision an over the top look and bring it to the runway using discarded, recycled, and upcycled materials was too great to pass up.”

Designed by Kate Major

Kate Major‘s design is a 90s grunge masterpiece made entirely from upcycled materials comprised of secondhand flannel shirts, the skirt contains original buttons, pockets, and sleeves from the original pieces. The top of the design features a vest made from pieced together leather, denim, and leopard print material.

Alone, the effect is jaw dropping, but Major elevated her design with painted embellishments and topped it off with something even more unconventional: kitchen utensils. The design features forks and spoons draped down the skirt and whisks drawing eyes to the shoulders, making for a look that is intriguingly busy and undeniably unique. 

As the Wardrobe Coordinator for the organization, Major came to Meow Wolf after working in costume design for Cirque du Soleil and The Wrigley Brothers’ Circus. Besides being the brains behind the Trashion Show, Major made her runway debut at Denver Fashion Week’s fall ’22 show.
