Controllable Construction Of Transition Metal Copper Phosphides And Their Complexes And Their Electrocatalytic Properties

the environment is more and more pollution with the use of traditional fossil energy.therefore,finding clean energy to replace traditional energy is impatientThe use of clean energy,reducing the use of traditional fossil energy,is conducive to reducing emissions of carbon-containing pollutants,and it also has a profound impact for the sustainable development of energy.This paper focuses the research object about transition metal copper phosphide,realizing the conversion of electrical energy into hydrogen energy by using electrocatalysis.copper phosphide nanomaterials is synthesized by using solvothermal method.this paper is focus research content as following:1.monodisperse Cu₃P nanosheets is realized the controllable construction by solvothermal method under mild conditions,and it is effect to relize controling of Cu₃P Pentagon nano material.with the increase of reaction time,reaction concentration and reaction temperature,the size is constantly increasing;monodisperse nanosheets and nanobelt materials are used for electrocatalytic hydrogen production test,when the current density is 10 m A cm^-2,the overpotential of nanobelts is as low as 189 m V,and the overpotential of monodisperse Cu₃P is 204 m V.2.Cu₃P nano meterials and Cu₃P/r GO composite materials is synthesised by solvothermal methode.the materials Cu₃P,Cu₃P/r GO and Pt/C have overpotentials of507 m V,366 m V,and 46 m V in the acidic system at a current density of 10 m A cm^-2respectively,the overpotential is 144 m V,154 m V,and 7 m V,respectively which the current density is 10 m A cm^-2in the alkaline system.The HER performance of Cu₃P/r GO has obvious advantages.cell capacity is 210 m Ah g^-1 and 600 m Ah g^-1 when Cu₃P and Cu₃P/r GO are used as cathode materials of lithium ion battery at the charge and discharge process.
