Coral-shaped copper-molybdenum-sulfur microsphere embedded graphene nano sheet and synthesis method and application thereof

Abstract

The invention discloses a coral-shaped copper-molybdenum-sulfur microsphere embedded graphene nano sheet and a synthesis method and application thereof. The synthesis method comprises the following steps of: synthesizing reducing graphene oxide by combining an improved Hummers method with an annealing reduction method; adding Na2MoO4 2H2O, CuCl2 2H2O and reducing graphene oxide into water, mixingand stirring, adding CH4N2S, stirring and performing ultrasonic treatment, then performing hydrothermal reaction; washing, drying and grinding the product obtained by hydrothermal reaction to obtain the coral-shaped copper-molybdenum-sulfur microsphere embedded graphene nano sheet. The coral-shaped copper-molybdenum-sulfur microsphere embedded graphene nano sheet has a good removal effect on degradation of organic pollutants which are difficult to biodegrade under a neutral room temperature condition and can be recycled, which does not need to adjust the pH value of a system to be 2-3 in the reaction process.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a coral-shaped copper-molybdenum-sulfur microsphere embedded with graphene nanosheets and a synthesis method and application thereof. Background technique [0002] Dyestuff is an important chemical raw material in industrial production, and it is also an essential chemical substance in contemporary life. The release of dyes into the water environment causes serious environmental pollution, which not only changes the color of the water body, but also affects human life and health through the food chain. For example, the artificial dye rhodamine B (RhB) has been found to be carcinogenic. However, the biodegradability of artificial dyes is very low, and it is difficult to remove dyes by conventional water treatment technologies based on biological treatment. Fenton technology, as a typical advanced oxidation technology, produces a large number of hydroxyl radicals during ...

Problems solved by technology

However, the biodegradability of artificial dyes is very low, and it is difficult to remove dyes by conventional water treatment technologies based on biological treatment. Fenton technology, as a typical advanced oxidation technology, produces a large number of hydroxyl radicals during the reaction. to destroy the molecular structure of the dye

However, due to the existence of the rate-limiting step in the classic Fenton reaction, not only the reactivity is poor under neutral conditions, but also there is a serious energy waste problem.

such as H 2 o 2 Finally, it is decomposed into oxygen by ineffective oxidation, making its utilization rate low; iron ions are continuously consumed, and finally a large amount of iron sludge is formed, which wastes resources and increases processing energy consumption
