Underlying Substrate Effect on Electrochemical Activity for Hydrogen Evolution Reaction with Low-Platinum-Loaded Catalysts

Abstract

Platinum is known as the best catalyst for the hydrogen evolution reaction (HER) but the scarcity and high cost of Pt limits its widespread applicability. In this work, we have uncovered the role of the underlying substrate on the HER activity of dispersed Pt atoms. A DC magnetron sputtering technique has been utilized to deposit transition metal (TM) thin films of W, Ti, and Ta as underlying substrates for an extremely low loading of Pt (
