Abstract
- In this study, a systematic investigation of MoS<subscript>2</subscript> nanostructure growth on a SiO<subscript>2</subscript> substrate was conducted using a two-stage process. Initially, a thin layer of Mo was grown through sputtering, followed by a sulfurization process employing the CVD technique. This two-stage process enables the control of diverse nanostructure formations of both MoS<subscript>2</subscript> and MoO<subscript>3</subscript> on SiO<subscript>2</subscript> substrates, as well as the formation of bulk-like grain structures. Subsequently, the addition of reduced graphene oxide (rGO) was examined, resulting in MoS<subscript>2</subscript>/rGO(n), where graphene is uniformly deposited on the surface, exposing a higher number of active sites at the edges and consequently enhancing electroactivity in the HER. The influence of the synthesis time on the treated MoS<subscript>2</subscript> and also MoS<subscript>2</subscript>/rGO(n) samples is evident in their excellent electrocatalytic performance with a low overpotential.
