Abstract

Hydrogen evolution reaction (HER) under non-extreme pH conditions is attractive but remains kinetically challenging, even for benchmark platinum (Pt) catalysts. Herein, we report that modification with a SiW9 polyoxometalate significantly enhances the HER activity of Pt in near neutral media, as demonstrated in a phosphate-borate buffer (pH 9.2). This enhancement originates from a synergistic co-tuning of the electronic structure and particle size of Pt.
