Preparation and Photocatalytic Activities of p-n Heterojunction Cu₂O/TiO₂ Nanoparticles

Abstract:

P25 is regarded as a good catalyst carrier and good photocatalyst. Cu2O has higher conduction and valence bands. In this paper the aim is to combined Cu2O with TiO2 to form p-n heterojunction structure to improve the photocatalytic efficiency. Cu2O-loaded TiO2 nanoparticles (Cu2O/TiO2) were prepared successfully by ultrasonication-assisted penetrate precipitation method. The modern sophisticate characterization method, TEM, SEM, XRD, etc, were used for catalysts characterization. The photocatalytic degradation kinetics of Cu2O-loaded TiO2 nanoparticles on methylene blue was systematically investigated.
