Cobalt-based metal organic framework material and application

The invention relates to a cobalt-based metal organic framework material with photocatalytic CO2 reduction performance and a preparation method. A solvothermal method is adopted for synthesis. Cobaltperchlorate hexahydrate, 1, 3, 5-trimethyl-2, 4, 6-tricarboxyl phenyl benzene, 1, 4-di (1-imidazolyl) benzene, N, N-dimethylformamide, fluoboric acid and water are synthesized in a polytetrafluoroethylene reaction kettle to obtain blue blocky crystals, and the blue crystals are washed and dried to obtain the photocatalytic material. The preparation method of the material is relatively simple. Theobtained catalyst has relatively good photocatalytic CO2 reduction capability, the selectivity of the reduction product CO can reach 77%, and the average yield of CO is 1124.8 [mu] mol g h. The material can be used as a cheap and efficient photocatalyst to replace precious metal, and the material shows a good application prospect in the field of photocatalysis. 本发明涉及一种具有光催化CO还原性能的钴基金属有机骨架材料以及制备方法。本发明采用溶剂热法合成，以六水合高氯
