Preparation Of Cu-BTC Supported Ni-Fe Derivatives And OER Performance Study

Serious environmental problems and drastic climate changes have placed urgent demands on clean and renewable energy.The decomposition of water into hydrogen(H₂)and oxygen（O₂）is expected to become an attractive way for the sustainable and high-purity production of hydrogen.It is the main method for the scalable application of hydrogen energy technology.However,the H₂ oxygen evolution reaction（OER）produced by electrolyzed water is a four-electron transfer,and the reaction kinetic process is relatively slow.So far,non-precious metal-based inorganic nanomaterials and functional molecular materials（Mo,Ni,Co,Cu,Fe）-based carbides have been thoroughly explored from transition metals for use in water decomposition.MOFs are widely concerned in electrolyzed water catalysts due to their interesting structure and their different physical and chemical properties.The experiment uses the metal organic framework Cu-BTC as the main body,Using MOCVD to load the metal organic precursors Fe Cp₂ and Ni Cp₂ into the interior of Cu-BTC,Electrocatalyst materials derived from copper oxide supporting iron and nickel at high temperature,Under the standard atmospheric pressure environment of 25℃,under the environment of 1M KOH solution,It was found that when the current density is 10 m A cm^-2,the overpotential is 270 m V,the electrochemical ECSA value is 4375 u Fcm^-2,and the impedance arc radius is also small,After working for 10 hours,the stability was preserved by 81%,and the stability was also excellent.Use XRD,SEM,TEM,XPS,etc.to test the characterize materials,It was found that the supported nickel and iron nanoparticles had a diameter of only 6 nm.This method provides a new method for the preparation of electrolyzed water catalyst and fills the vacancy of OER catalyst in electrolyzed water.
