A team led by Professors JIANG Qing and YANG Chuncheng from the School of Materials Science and Engineering at Jilin University (JLU) made significant progress in the development of sub-3-nanometer high-entropy alloy (HEA) nanoparticles with triple functionalities for efficient electrolytic hydrogen production.

The related findings, entitled Sub-3-nm High-Entropy Alloy Nanoparticles with Triple Functionalities for Efficient Electrolytic Hydrogen Production, were published in Advanced Materials on July 31.

This study develops sub-3-nm PtRuFeCoNiCu high-entropy alloy nanoparticles via a 0.5-second ultra-fast thermal shock method, which achieves record-low overpotentials for alkaline hydrogen evolution. The catalyst also demonstrates strong potential for large-scale hydrogen production.

Doctoral student ZHANG Ying is the first author of the paper. Professors CHEN Zhiwen, YANG Chuncheng, and JIANG Qing are corresponding authors.
