Enhancing the catalytic activity of bulk MoS towards hydrogen evolution reaction by the formation of MoS-MoO-ReO heterostructure.

Two-dimensional transition metal dichalcogenides (TMD) are promising cost-effective catalysts for electrochemical/photoelectrochemical hydrogen evolution reactions (HER). One of the strategies to enhance the inherent HER activity of a catalyst is to form heterostructures. Herein, a facile thermal treatment method is reported for the synthesis of a novel heterostructure catalyst, Molybdenum disulphide-Molybdenum trioxide-Rhenium oxide (MoS-MoO-ReO), for HER.
