A simple and effective electrostatic method has been used to attach MoO3 belts onto a graphene template. The MoO3/graphene composite was annealed under a H-2/Ar atmosphere; the obtained MoO2 maintained its original structure and exhibited microstructures such as flaws, etc. We investigated the electrocatalytic behavior of the MoO2/graphene composite towards the hydrogen evolution reaction.
