Abstract

The invention discloses a preparation method of a nickel-based heterogeneous metal organic framework material and application of the nickel-based heterogeneous metal organic framework material. Two porous metal organic framework materials are obtained by self-assembling organic ligands including 2, 5-thiophenedicarboxylic acid (TDA), 2, 5-furandicarboxylic acid (FDA), nickel sulfate, deionized water, N, N-dimethylformamide (DMF) and a mixed solution of HBF4 with the mass concentration of 37%; and the synthetic materials are assembled into a three-electrode system to carry out electrocatalytic methanol oxidation test. The metal organic framework material has the advantages of simple synthesis process, high crystal purity, high yield, novel structure and large porosity. According to experimental test data analysis, the Ni-MOF1 material and the Ni-MOF2 material both have excellent electro-catalytic methanol oxidation activity, and the composite material of ( the Ni-MOF1 / Ni-MOF2) has more excellent methanol oxidation activity.

Description

technical field [0001] The present invention relates to two kinds of metal organic framework materials (Ni-MOF1, Ni -MOF2), two cases of Ni-MOF showed excellent methanol oxidation activity through the preparation of catalyst electrode materials. At the same time, two cases of Ni-MOF were composited to obtain heterogeneous composite materials. It has more excellent performance on methanol oxidation (MOR). Background technique [0002] Energy crisis and environmental problems have become difficult problems that human beings must face and solve in the 21st century. The increase in the consumption of fossil fuels has gradually led to the deterioration of the earth's environment and the depletion of renewable resources. Due to environmental pressure, people's demand for new energy systems is becoming more and more urgent. Hydrogen energy is a green, clean and efficient renewable energy. Renewable energy has become a focus of attention. Electrocatalysis is a simple and efficien...
