Abstract

The invention discloses preparation and application of a CdS / MoS2 / C60C(COOH)2 ternary composite, and belongs to the technical field of inorganic material synthesis. The preparation comprises the stepsof preparing CdS and MoS2 nanomaterials separately by a simple solvothermal method, then combining the surfaces of the two nanomaterials to form a CdS / MoS2 binary composite, and finally, compoundingthe CdS / MoS2 binary composite with a C60 carboxylic acid derivative (C60C(COOH)2) through adsorption, so as to obtain the ternary composite containing different C60C(COOH)2 loadings. Fullerene is freeof toxicity and can achieve better biocompatibility and electrophilicity after being modified with carboxyl functional groups, and the surface of fullerene is loaded with CdS nanomaterials and a cocatalyst (MoS2) to promote the separation efficiency of electrons and holes in semiconductor materials, increase the degradation rate of rhodamine B of CdS / MoS2 under visible light effectively, and enhance the photocatalytic activity of semiconductor nanomaterials.

Description

technical field [0001] The invention belongs to the technical field of inorganic material synthesis, and in particular relates to a simple method for preparing CdS / MoS 2 / C 60 C(COOH) 2 The method of the composite material and the application of the composite material to the degradation of Rhodamine B under visible light. Background technique [0002] At present, the huge consumption of traditional fossil fuels such as coal, oil and natural gas has not only caused energy shortages, but also caused serious environmental pollution, and even directly threatened the survival of human beings. Although the traditional pollutant treatment methods in solving environmental problems have high efficiency, they will inevitably produce environmentally harmful by-products during the treatment process, and cannot be used sustainably. In recent years, researchers have discovered that the physical and chemical processes of some semiconductor materials can be applied to the generation of c...
