Abstract

The article introduces a novel one-step hydrothermal method to synthesize NiS2@MoS2 nanocrystals, consisting of a core of NiS2 nanocubes and a shell of few-layered MoS2 nanosheets. This method not only simplifies the synthesis process but also significantly enhances the electrocatalytic performance of the nanocrystals for hydrogen evolution reactions. The study explores the morphological and structural characteristics of the nanocrystals, highlighting their improved activity and stability compared to pure NiS2 and MoS2. Additionally, the method is extended to synthesize CoS2@MoS2 and FeS2@MoS2 nanocrystals, demonstrating its versatility and potential for wide applications in clean energy production.
