Fabrication of Ce-ReS₂ by Molten Salt for Electrochemical Hydrogen Evolution

Abstract

Renewable and economical generation of hydrogen via electrochemical methods shows great potential in addressing the energy crisis. In this study, an emerging molten salt method was adopted for the synthesis of a cerium-modified rhenium disulfide nanosheet for electrical hydrogen evolution reactions. The prepared 1% Ce-doped rhenium disulfide (ReS₂) sample showed promoted hydrogen evolution performance in both acid and alkaline electrolytes compared to bare ReS₂. Generating of abundant defects in ReS₂ exposed more reaction active sites. Moreover, adding cerium accelerated the hydrogen evolution dynamics. Hopefully, this work will offer new insight into developing ReS₂-based electrocatalysts for hydrogen evolution reactions.
