Abstract

The invention discloses a preparation method of a hydrogen evolution electric catalyst based on a metal-organic framework compound. The method includes the following steps that 1, cupric acetate aquo-complex Cu (OAc) <2>H<2>O is dissolved in acetic acid for preparing a cupric acetate solution; 2, trimesic acid (H<3>BTC) particles are dissolved in absolute ethyl alcohol for preparing a trimesic acid solution; 3, the trimesic acid solution is transferred to and mixed with the cupric acetate solution; 4, the mixed solution is subjected to ultrasonic operation; 5, the mixed solution is placed in a centrifugal tube for centrifugal operation and activating treatment; 6, a centrifugal product obtained after activating treatment is placed in a drying oven for being dried; 7, after samples and organic solvent are mixed according to proportion, the Cu-MOF@Nafion hydrogen evolution catalyst is obtained. The obtained Cu-MOF@Nafion hydrogen evolution catalyst has unique physical properties of good transmission protons, good electrochemical stability is achieved, efficiency of a hydrogen evolution reaction can be improved, and the recycling service life can be greatly prolonged.

Description

technical field [0001] The invention relates to a method for preparing a hydrogen evolution electrocatalyst based on a metal organic framework compound, in particular to a method for preparing a Cu-MOFNafion hydrogen evolution catalyst. Background technique [0002] According to data from the National Bureau of Statistics, from 2011 to 2014, China's GDP grew at an average annual rate of 8.0%, shifting from high-speed growth to medium-to-high speed growth. Year-by-year, 2011 increased by 9.5% over the previous year, 2012 and 2013 increased by 7.7%, 2014 increased by 7.3%, and in the first half of 2015 increased by 7.0%. my country's economy is developing rapidly and the industrial level is constantly improving. However, a series of social and environmental problems have emerged in this process, among which the energy crisis and environmental pollution are particularly serious. To solve this problem, people pay more and more attention to the development of clean energy, such ...
