Three dimensional heterostructure of CuO nanoparticle decorated reduced graphene oxide (rGO) was prepared by a facile and cost-effective technique. The structure and electrochemical properties of the CuO-rGO heterostructure composites were evaluated by various techniques. Transmission electron microscopy image analysis confirmed the presence of CuO nanoparticles onto the surface of the rGO sheets. It was also noticed that the electrochemical properties were dependent on the morphology of the heterostructure. The CuO-rGO heterostructure showed better hydrogen peroxide sensing performance as compared to the pure CuO nanoparticle. The sensitivity and limit of detection (LoD) were found to be 57.6 μA mM-1 cm-2 and 4.3 nM. The CuO-rGO heterostructure also showed good selectivity in the presence of various interfering electrolytes like ascorbic acid, dopamine, uric acid and glucose.
