Professor Yong-Tae Kim’s team at POSTECH pioneers a novel approach to water electrolysis catalysts for green hydrogen production.
Originally, the term “Sherpa” denoted a hill-tribe of Tibetan descent, but it has since become synonymous with guides on Mount Everest, the world’s highest and most rugged mountain. Much like these Sherpas, research into the demanding task of developing catalysts for hydrogen production is making substantial progress and has earned recognition as the featured cover article in a prominent international journal.
Professor Yong-Tae Kim from the Department of Materials Science and Engineering and the Graduate Institute of Ferrous & Eco Materials Technology, and Kyu-Su Kim, a doctoral student from the Department of Materials Science and Engineering at Pohang University of Science and Technology (POSTECH), collaborated on a research project that offers a promising direction for the future development of catalysts for water electrolysis*1. Their study has garnered considerable academic attention and was showcased as the cover article in ACS Catalysis, an international journal in the field of chemistry.
Water electrolysis, a method for producing hydrogen from the abundant resource of water, emerges as an environmentally friendly technology that produces no carbon dioxide emissions. However, this process faces limitations due to its reliance on precious metal catalysts such as iridium (Ir), rendering it economically unfeasible. Researchers are actively exploring the development of catalysts in the form of metal alloys to address this challenge.
