In recent ten years, we has been committed to developing electrocatalytic systems in proton exchange membrane fuel cells and other battery series, using electrochemical in-situ synchrotron radiation technology to reveal the fine structure of catalytic materials and catalytic mechanism. As first author,  we published 11 papers including PNAS, JACS, Nano Lett., Chem. Sci. and other international well-known journals (9 papers in SCI Region I). The total citations were more than 1224 times, H index was 12, the highest citations of a single paper were 283, 2 papers were selected as ESI highly cited papers, 1 paper was ACS Energy Letters the most reading articles.
