On August 5, the research work led by Professor Li Qing, Chinese supervisor of ICARE from the School of Materials Science and Engineering, was published online in Science Advances. The paper, entitled Triggering charge redistribution-induced oxygen spillover mechanism in VOx-supported IrSn alloy toward industrial water electrolysis, reports an amorphous vanadium oxide-supported iridium-tin alloy catalyst with an oxygen spillover effect driven by charge redistribution, which is applicable to industrial-scale water electrolysis.

Lin Zijie, a PhD student from the School of Materials Science and Engineering, serves as the first author, while Professor Li Qing is the corresponding author. The School of Materials Science and Engineering and the State Key Laboratory of Material Forming and Mold Technology are the first affiliation and the first corresponding affiliation. This research was supported by grants including the Excellent Young Scientists Fund of the National Natural Science Foundation of China and the National Key Research and Development Program of China.

The team proposes viable new strategies for the fabrication of oxide-supported iridium-alloy catalysts and the design of PEM water electrolysis devices featuring low noble-metal loading, high catalytic activity and outstanding stability.
