Growth of noble metal nanoparticles on single-layer TiS2 and TaS2 nanosheets for hydrogen evolution reaction

Abstract

The preparation of single-layer TiS₂ and TaS₂ nanosheets is realized by optimizing the electrochemical lithium interaction and exfoliation method. As a proof of concept, Pt and Au nanoparticles are grown on the aforementioned ultra-thin nanosheets to form functional composites. Notably, the Pt–TiS₂ hybrid presents good electrocatalytic activity in the hydrogen evolution reaction.
