- Development of electrode with superior hydrogen/oxygen generation reaction performance than benchmark electrode using a multi-circular micro-cluster structure with a greatly improved surface area -

As concerns about ever-increasing levels of greenhouse gas emissions increase, the search for sustainable and clean energy resources has become essential to gradually reduce and replace the use of fossil fuels. Hydrogen makes up 75% of the mass of the universe. Water (H2O), which is one of the most common elements on Earth and accounts for 70% of the Earth's surface, also contains a large amount of hydrogen. Hydrogen energy is attracting attention as an excellent renewable energy source because of its high energy density and zero carbon emission. It is already steadily entering our daily lives. Hydrogen engine-based vehicles, trains, ships, and airplanes are being developed one after another. Hydrogen energy-based electricity can be used in ordinary homes as well.

This research was carried out with the support of Brain Korea 21 Plus (BK-21 ) promoted by the National Research Foundation of Korea and the Ministry of Education, a key research institute project, and Kwangwoon University. The research results were published in the scientific journal Applied Materials Today (JCR Category Q1 MATERIALS SCIENCE, MULTIDISCIPLINARY, IF: 8.663) in July 2022 under the name “Electron enriched ternary NiMoB electrocatalyst for improved overall water splitting: Better performance as compared to the Pt/C || RuO2 at high current density”.
