Embodiment 1

[0030] Example 1: A CoFeMOF-P / b-CNF composite electrocatalyst and its preparation method

[0031] A CoFeMOF-P / b-CNF composite electrocatalyst, the CoFeMOF-P / b-CNF electrocatalyst includes Co salt, Fe salt and bacterial cellulose membrane, and the CoFeMOF-P / b-CNF electrocatalyst is subjected to high temperature through phosphorus salt Phosphating.

[0032] Its preparation method is as follows:

[0033] S1. Prepare 10 mL of a mixed solution of N,N-dimethylformamide (DMF) and ethanol at a volume ratio of 1:1, and add 11 mg / mL of Co(CH 3 COO) 2 •6H 2 O, 6 mg / mL FeCl 3 •6H 2 O, 6 mg / mL terephthalic acid and 50 mg / mL polyvinylpyrrolidone were dissolved evenly at room temperature, then 1 g of bacterial cellulose membrane was added, shaken and adsorbed for 12 hours, and transferred to a polytetrafluoroethylene reactor , heated to 150°C for hydrothermal reaction for 48 hours; after cooling to room temperature, washed with DMF three times, and dried the brown-black product in an o...

Abstract

The invention belongs to the technical field of new materials, and particularly relates to a CoFeMOFP/bCNF composite material electrocatalyst and a preparation method thereof. The technical scheme isthat the CoFeMOFP/bCNF electrocatalyst comprises a Co salt, a Fe salt and a bacterial cellulose membrane, and is subjected to high-temperature phosphorization through a phosphorus salt. According to the CoFeMOFP/bCNF composite material electrocatalyst and the preparation method thereof, NF prepared by taking a bacterial cellulose membrane as a precursor has the advantages of multiple pore channelsof a three-dimensional structure and high toughness, and is used as a conducting wire between a CoFeMOF skeleton supporting material and MOFs particles, so that the morphology completeness of the MOFs material is ensured, and the conductivity and the electrocatalytic capability are improved.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a CoFeMOF-P / b-CNF composite material electrocatalyst and a preparation method thereof. Background technique [0002] Energy is an inexhaustible driving force for human development and an important criterion for measuring a country's economic development and people's quality of life. In the past few decades, the rapid growth of population, the popularization of automobiles, and the increase in the use of machines have led to a decline in the reserves of fossil fuels, and eventually energy will be exhausted. Not only that, the use of fossil fuels has led to serious environmental pollution and global warming. Therefore, in recent years, people have vigorously developed environmentally friendly new energy sources. A clean, non-polluting, and sustainable resource—hydrogen energy is recognized as the most promising alternative to fossil fuels in the 21st century. E...
