Number of hits:Recently, Professor Tian Yang and his team from the Department of Chemistry, CNU freely submitted a paper entitled Spatial Configuration of Fe-Co Dual-sites Boosting Catalytic Intermediates Coupling Toward Oxygen Evolution Reaction, with Capital Normal University as the first unit, in the top international journal Proceedings of the National Academy of Sciences (PNAS).
Professor Tian Yang and his team constructed two "Fe-Co" Dual-sites catalysts─stereo-Fe-Co DSC in stereo-Fe-Co DSC and planar-Fe-Co DSC─which shows excellent catalytic performance for oxygen production by electrolysis of water, with a minimum overpotential of 190 mV (at 10 mA/cm²) and a stability of more than 160 hours. This suggests that it may be a cost-effective catalyst for water electrolysis. Through a large number of experimental characterization and theoretical calculations, it is confirmed that the prepared catalyst is conducive to the dehydrogenation of reaction intermediates, promotes their coupling toward oxygen release, and thus improves the efficiency of water electrolysis.
The research is co-worked by the Department of Chemistry of our university, Beijing Academy of Science and Technology, and Tsinghua University with financial support from the National Natural Science Foundation of China (52172096, 22375131) and others, and Zhang Taiyan, a master's student in the Department of Chemistry, is the first author of the paper.
