A simple solution-based synthesis route, based on an oxidation–reduction reaction between graphene oxide and SnCl₂•2H₂O, has been developed to produce a SnO₂/graphene composite. In the prepared composite, crystalline SnO₂ nanoparticles with sizes of 3–5nm uniformly clung to the graphene matrix. When...
