Abstract
Layered transition metal dichalcogenides and their hybrids with reduced grpahene oxide (rGO) have attracted much interest due to many potential applications for electrode materials in Li ion batteries and supercapacitors and electro-catalysts for hydrogen evolution reaction. Among them, synthesis of VS2 sheets and VS4/rGO hybrid via a hydrothermal reaction was recently reported, whereas VS2/rGO hybrid sheets have not been reported. In this study, we report VS2/rGO hybrid sheets after annealing VS4/rGO hybrid materials at 350 °C. The conversion of VS4 to VS2 on rGO sheets after annealing is attributed to a thermal cleavage of VS4.
