Facile synthesis of three-dimensional flower-like MoO2-graphene nanostructures with enhanced electrochemical performance

Novel three dimensional MoO2-graphene (MoO2-G) flower-like nanostructures are synthesized via a facile hydrothermal reaction. It has been shown that the MoO2-G demonstrates enhanced supercapacitive performance compared to pure MoO2 particles. The excellent electrochemical performance is attributed to the introduction of graphene and a hierarchical nanostructure, providing a large surface area and low equivalent series resistance.
