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) wit
