Preparation method and application of environment-friendly core shell one-dimensional nanometer copper wire-organic metallic framework ZIF-8 composite catalyst

Abstract

The invention discloses an environment-friendly core shell one-dimensional nanometer copper wire-organic metallic framework ZIF-8 composite catalyst and a preparation method and application of the environment-friendly core shell one-dimensional nanometer copper wire-organic metallic framework ZIF-8 composite catalyst. A microwave induction coring heating synthesis method is adopted, N, N-dimethylformamide is used as a solvent, polyvinylpyrrolidone is used as a trapping agent, a copper wire is used as a one-dimensional structure loading carrier, the environment-friendly core shell one-dimensional nanometer copper wire-organic metallic framework ZIF-8 composite catalyst is synthesized fast, the decomposition rate of the catalyst on ammonia borane in an ammonia borane decomposition catalytic reaction is 71 percent, and the good catalytic activity is shown. The preparation method of the catalyst is simple, and environmental pollution is small. An organic metallic framework ZIF-8 is combined with a non-precious metal copper nanometer wire with the good conductivity and certain catalytic performance, and the catalytic performance of the material of this kind is greatly improved. The material is potentially applied to energy storage, pollution gas absorption, sewage treatment, new energy development and other fields.

Description

technical field [0001] The invention relates to the technical field of photocatalysts, in particular to an environment-friendly core-shell one-dimensional nanostructure nano copper wire-organometallic framework ZIF-8 composite catalyst and its preparation method and application. Background technique [0002] The energy problem is one of the important challenges facing the world at present, and solving this problem is of great significance for my country to implement sustainable development, ensure national security, and build a harmonious society. China has become the world's second largest energy consumer, and will likely surpass the United States to become the world's largest energy consumer in the future. China's per capita energy resources are very low. The per capita possession of coal and hydropower resources is only 50% of the world's average level, and the per capita oil and natural gas resources are only about 1 / 15 of the world's average level. The occurrence of en...
