Hydrogen Evolution Catalyzed by Cu₂WS₄ at Liquid–Liquid Interfaces

Abstract

The present study reports, for the first time, both a facile synthesis for ternary Cu₂WS₄ nanocubes, which were synthesized by a simple and low-cost hot-injection method, and the hydrogen evolution reaction at a biomembrane-like polarized water/1,2-dichloroethane interface catalyzed by Cu₂WS₄ nanocubes. The rate of hydrogen evolution reaction is increased by about 1000 times by using Cu₂WS₄ nanocubes when compared to an uncatalyzed reaction.
