摘      要：Graphene-doped CuO(rGO-CuO)nanocomposites with flower shapes were prepared by an improved solvothermal *** samples were characterized by X-ray diffraction,X-ray photoelectron spectroscopy and UV–visible *** active species in the degradation reaction of rGO-CuO composites under ultrasonic irradiation were detected by electron paramagnetic *** the basis of comparative experiments,the photodegradation mechanisms of two typical dyes,Rhodamine B(Rh B)and methyl orange(MO),were *** results demonstrated that the doped CuO could improve the degradation *** catalytic degradation efficiency of rGO-CuO(2:1)to rhodamine B(RhB)and methyl orange(MO)reached 90%and 87%respectively,which were 2.1 times and 4.4 times of the reduced graphene *** the first-principles and other theories,we give the reasons for the enhanced catalytic performance of rGO-CuO:combined with internal and external factors,rGO-CuO under ultrasound could produce more hole and active sites that could interact with the OH·in pollutant molecules to achieve *** rGO-CuO nanocomposite has a simple preparation process and low price,and has a high efficiency of degrading water pollution products and no secondary pollution *** has a low-cost and high-efficiency application prospect in water pollution industrial production and life.
