Growth of noble metal nanoparticles on single-layer TiS_2 and TaS_2 nanosheets for hydrogen evolution reaction

摘要

The preparation of single-layer TiS_2 and TaS_2 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-TiS_2 hybrid presents good electrocatalytic activity in the hydrogen evolution reaction.
