title: Effects of architectures and H2O2 additions on the photocatalytic performance of hierarchical Cu2O nanostructures.
abstract: Cu2O hierarchical nanostructures with different morphologies were successfully synthesized by a solvothermal method using copper (II) nitrate trihydrate (Cu(NO3)2⋅3H2O) and ethylene glycol (EG) as initial reagents. The obtained nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area test, and UV-vis spectroscopy. The synthesis conditions (copper source, temperature, and reaction time) dominated the compositions and the formation of crystals with different morphologies. The visible light photocatalytic properties of as-prepared Cu2O nanostructures were investigated with and without hydrogen peroxide (H2O2), and the effect of H2O2 were evaluated by monitoring the degradation of methyl orange (MO) with various amounts of H2O2. It was revealed that the degree of the photodegradation of MO depends on the amount of H2O2 and the morphology of Cu2O.
