Dr. Yun received his Ph.D. degree in College of Chemical Engineering from the Zhejiang University of China in 2022. His research focuses on the synthesis and design of nanomaterials, particularly the multimetallic alloy or oxides, which could be applied in proton exchange membrane electrolyzers, oxygen evolution, and oxygen reduction. And the relationship between these nanocatalysts and the electrocatalytic performance is investigated by some microstructural characterizations. Dr. Yun is working with Dr. Wang to design new nanocatalysts and electrolyzers for electrocatalysis.
