Professor Yoon Kyung-byung published article in “Science” with the development of high efficient CO₂

- Professor Yoon Kyung-byung published article in world’s prestigious academic journal “Science” and headed one step ahead for solution towards global warming with the development of high efficient CO₂-




Sogang University Department of Chemistry professor Yoon Kyung-byung (head of the Korean Center for Artificial Photosynthesis, KCAP) developed groundbreaking material that can collect large amount of CO₂from waste gas and atmosphere (also known as SGU-29) for the first time in the world. This research result by professor Yoon Kyung-byung as corresponding author was published in online version of the world’s prestigious science journal “Science” on October 16.

Research team of professor Yoon Kyung-byung has been carrying out research on artificial photosynthesis with the support from the project of climate change response development of basic/fundamental technology organized by Ministry of Science, ICT and Future Planning and National Research Foundation of Korea. In the future, with the development of SGU-29, will lead a way to not be effected by the moisture and collect CO₂at low cost. This has let the actualization of technology to go one step ahead towards groundbreaking methods for reducing global warming.

CO₂has been rapidly accelerating global warming and climate change due to the green-house gas that arise when burning fossil fuels such as coal, petroleum, natural gas and so on. Also by making rapid acidification of seawater, marine ecosystem is also being desolated. Therefore it is important to collect CO₂then convert them into fuel again, however, existing CO₂absorbents had problems of significant decline in absorption performance, which has been influenced by the moisture that exist together with CO₂.

By synthesizing through hydrothermal reaction, research team of professor Yoon Kyung-byung developed very stable SGU-29 on moisture and made it possible to absorb large amount of CO₂ at low cost. SGU-29 is far greater than the area that is being adsorbed by CO₂compared to the area that is being adsorbed by the moisture, so regardless of moisture adsorption availability, as the zeolite type mesoporous material, can adsorb CO₂well. The mass production is possible from this year so starting this end of the year, it is expected to go through the process of collecting CO₂.

Especially the name SGU-29 comes from the English initials of Sogang University(SGU) and named after its main element of structure, which is Cooper (Cu), and its atomic number, which is 29, so named as SGU-29.

Professor Yoon Kyung-byung said, “This research result is expected to be an ideal absorbent that satisfies all the required conditions and makes it possible to produce large amount, so this can be used for collecting CO₂right away.” And added, “I wish that this material can immediately be used for collecting CO₂from waste gas that arise in the industrial circles and contribute towards improving the environment.”
