摘要：

CuO-CeO2/Graphene Oxide(GO) nanocomposite photocatalyst was fabricated by a facile dip-molding and ultrasound assisted process, which has a high specific surface area and photo activity. The as-prepared nanocomposites were characterized by N-2 adsorption-desorption, X-ray diffraction, UV-vis diffuse reflectance spectra, HRTEM, and FE-SEM. The nanocomposite showed better catalytic activity than pure CuO and CuO/GO toward the degradation of methyl orange (MO) in the presence of H2O2 under visible light irradiation (lambda > 400 nm). With the efficient interelectron transfer and superior adsorption capacity which were attributed to the amazing properties of the GO and nanoparticles, it's a promising photocatalyst in managing some chemically stable azo dyes in water.
