Key Points

The study aims to improve the efficiency of the hydrogen evolution reaction under non-extreme pH conditions using modified platinum catalysts.
Utilized SiW9 polyoxometalate to modify platinum catalysts.
Evaluated the performance in buffered electrolytes under varying pH conditions.
Analyzed the kinetics of the hydrogen evolution reaction.
Modification with SiW9 led to a significant increase in catalytic activity compared to unmodified platinum (exact rates not specified).
Improvements were noted across a range of buffered electrolytes, highlighting robust performance in diverse conditions.

Implication

Shows improved hydrogen evolution in buffered electrolytes using modified platinum, indicating a potential advancement in catalytic performance.

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...
