IBS Researchers Developed New Catalyst That Produces Hydrogen Peroxide (H2O2) Using Only Oxygen and Water

A catalyst has been developed that can increase the production efficiency of hydrogen peroxide (H2O2), a key material for the chemical and pharmaceutical industries, by up to eight times. The research team with Hyun Teak-hwan (Chair-professor at Seoul National University, Department of Chemical and Biological Engineering) and Sung Yeong-eun (Professor at Seoul National University, Department of Chemical and Biological Engineering), who are the leader and vice leader of Nanoparticle Research Group of Institute for Basic Science respectively, collaborated with a team of Yoo Jong-seok professor at University of Seoul to develop an electrocatalyst that can produce hydrogen peroxide eco-friendly using only oxygen and water. As a result, hydrogen peroxide can be produced with a catalyst that is more than 2000 times cheaper than the existing noble metal catalyst, so it is evaluated as a ‘killing three birds with one stone’ technology that solves all of the cost, efficiency and environmental issues. ▲ Leader Hyun Teak-hwan (left) and Vice Leader Sung Yeong-eun (right) attended to present the major achievements. Hydrogen peroxide is widely used in household goods such as toothpaste and dish detergent, as well as in medical sites that require sterilization and in semiconductor processes that wastewater treatment and removal of impurities. Industrial hydrogen peroxide is mainly produced by the anthraquinone process. However, the anthraquinone process* uses expensive palladium catalysts, which not only consumes a lot of energy, but also has the limitation that organic substances are generated as by-products and cause environmental pollution. Therefore, as the demand for hydrogen peroxide increases with the development of ultra-precision semiconductors and mechanical parts, there is a need for a sustainable process that can produce hydrogen peroxide with cheap and high efficiency. * Anthraquinone process: A process of producing hydrogen peroxide by sequentially reducing and oxidizing anthraquinone dissolved in an organic solvent in the presence of a catalyst. Expensive palladium catalysts are required in large quantities, and excessive energy is consumed in each step, resulting in low energy efficiency. In addition, since organic solvents are generated as by-products, there is a limit that causes environmental pollution. ▲ Control of catalytic activity through structure control around cobalt atoms (Image provided by IBS) The research team devised an inexpensive catalyst that could electrically produce hydrogen peroxide using water (H2O) and oxygen (O2) without the need for complex steps. The catalyst, developed by the researchers, is in the form of putting a cobalt (Co) atom on two-dimensional graphene. Unlike conventional catalysts, they are inexpensive as they use cheaper cobalt atoms instead of precious metals such as platinum and palladium. When the developed cobalt atom/graphene catalyst is added to an aqueous solution of saturated oxygen and subjected to electricity, hydrogen peroxide can be produced without adding any other compound. This catalyst has produced up to eight times higher productivity than the expensive noble metal catalysts known to be the most efficient. With 1kg of catalyst, it is capable of producing 341.2 kg of hydrogen peroxide per day. In addition, it was confirmed that even after the experiment for continuously producing hydrogen peroxide for more than 110 hours, it maintains more than 98% of the initial performance. “The idea is based on the finding that an inexpensive atom such as iron, cobalt, or nickel effectively mediates electrochemical reactions when stabilized on graphene. It was confirmed that the activity of the catalyst could be controlled at the atomic level and even justified by calculation chemistry. Consequently, by changing the structure around the cobalt atoms, the team was able to develop a catalyst with world-class hydrogen peroxide production ability.” Said Sung Yeong-eun vice leader. ▲ Performance Comparison of Catalysts Developed by Researchers and Conventional Catalysts (Image provided by IBS) The catalyst developed by the researchers is a heterogeneous catalyst**, which is cheaper than a homogeneous catalyst and is eco-friendly because it does not generate waste catalyst and it can be recycled after the reaction. This work means a lot academically in the way of the world's first discovery of a principle for increasing the activity of heterogeneous catalysts at the atomic level. The researchers expect the catalyst to be used in a wide variety of chemical processes as it can synthesize products stably and environmentally at both room temperature and atmospheric pressure. **Heterogeneous catalyst: When a catalyst has the same form with the reactants and products, it is called a homogeneous catalyst. In this time, the reaction proceeds in the form of all catalyst, reactants and products dissolved in solvent. On the other hand, heterogeneous catalysts have the advantage that they can be recovered and recycled after the reaction as the reactants and products differ from each other in the gaseous or liquid state. “Hydrogen peroxide, the world's top 100 industrial chemicals, can now be produced environmentally and economically. It is expected to improve productivity by applying hydrogen peroxide production as well as many chemical reactions using catalysts.” Said Hyun Teak-hwan leader. Meanwhile, the results of the research were published in Nature Materials (IF 39.124), the world's leading journal in materials, on the January 14 in Korean time.

EBS Well-Made Documentary ‘Singers – Laugh and Cry with the Times’ Press Conference

On December 22, EBS (CEO Kim Myung-Joong) announced a specially designed documentary ‘Singers – Laugh and Cry with the Times’ (10 episodes) during the press conference held at Sookmyung Women's University. ‘Singers – Laugh and Cry with the Times’ (hereinafter ‘Singers’) is a music & interview documentary that intensively sheds new light on the great singers who soothed the anxiety and sorrows of the people and sometimes encouraged their hope and courage throughout the turbulent modern history. In particular, ‘Singers’ is a biography with a bold line that finds the value of musical DNA and rediscovers the singers who have comforted people in the ages before the BTS craze that swept the world today. ▲ ‘Singers’ Season 1, which recorded Korean modern and contemporary history with singers' voice and songs, was revealed on 22. ‘Singers’ is composed of only singers’ songs and real interviews without narration. EBS produced a teleprompter for video for the first time in Korea and performed a special shooting where the performer looks directly at the camera. And it made viewers feel like they are vividly meeting stars through TV. In addition, high-quality audio, such as a hyper-cardioid condenser mic, was used to show the music as if we are at the live concert of the singers. ‘Singers’ first episode, aired at 9:35 pm on Sunday, December 22, was opened by a folk singer Song Chang-Sik. After a long absence, Song Chang-Sik, who slugged the 70s as a symbol of youth culture, such as <Whale Hunting> and <Why Do You Call Me?>, talked about a story which has never been done in front of the camera. ▲ Singer Hye-Eun-Yi ▲ Singer Lee Eun-Ha ▲ Singer Jeon Young-Rok ▲ Han Sang-Ho, CP at EBS and General Director of ‘Singers’ ■ “I wanted to play my music with our words and language, just like writing an old poem pleasantly.” We can meet Song Chang-Sik, who pursued Korean colors in a series of hit songs, including <Ga Na Da Ra>, <A Day of Sparrow>, <Azure Days>, <We are>. The second episode, which will be broadcasted on December 29, will be handed by Yang Hee-Eun, who presented a deep resonant sound to the times. Yang Hee-Eun found an echo in all ages’ hearts through the folk songs like <Morning Dew> and <Evergreen Tree> as well as popular songs with unique emotions such as <About the Loneliness Called Love> and <Han Gye Ryeong>. This time, she will present another impression with serious interview. Besides the broadcaster Yang Hee-Eun who is loved by various entertainment programs and radio, the true character of the singer Yang Hee-Eun and the reason why she is a godmother of folk song will be revealed through the ‘Singers’. Korea’s first singer for video, Hye Eun-Yi, had taken the love of the whole nation by causing ‘Hye Eun-Yi Syndrome’ with a series of hit songs such as <You Wouldn’t Know>, <I Really Really Like You>, and <Third Han River Bridge>. Her popularity as a fashion icon, such as a short cut hair craze called ‘wind hair’, was greater than any other female singers. Still singing with a little girl’s heart, Hye Eun-Yi can be confirmed through the third episode of ‘Singers’. ▲ EBS first developed and introduced a teleprompter designed to keep viewers and interviewers at the same eye level. ■ “The movie is my father, and the song is my mother. My musical and sensory talent came from 98% of my family's genes. I do not want to deny my roots.” Jeon Young-Rok, who is known as an all-round entertainer and the originator of a huge fan base of teenage girls called ‘Oppa Budae’, is the one who always meets fans at the front line. Recently, he has challenged fishing life through the evening program of public TV and is expecting his second heyday. He said that ‘Singers’, which looks back on the song life, is a welcome program like rain for a drought. Meanwhile, Jeon Young-Rok's music diary, such as holding a concert at Cheongju CJB Media Center on December 29, 2019, is still in progress. ■ “I like to challenge myself. My heart is as excited as waiting for a loved one. ” The confession of disco queen and singer Lee Eun-Ha, who has challenged various genres such as ballad, disco, rock and jazz, is beautiful. Overcoming the illness and restoring the current health, she boasts colorful colors like a chameleon. In addition, you will be able to meet 10 great singers, including Lee Eun-Ha, Han Dae-Soo, Kim Soo-Chul, Song Dae-Gwan, and Lee Jang-Hee until February next year. ▲ PD Jeon Young-Geon also attended the joint interview and told the story behind the production. ▲ EBS exhibited photographs of moments during filming and paid tribute to the singers who shed light on an era.
