Design,Synthesis And Studies Of Copper,Cobalt Nickel Complexes With Electrocatalytic Or Photocatalytic Hydrogen Production Properties

With the progress of society and the rapid development of economy,the demand for energy from mankind is increasing day by day.The development of new energy sources to replace fossil fuels?coal and petroleum?has become an inevitable trend.The use of hydrogen energy can effectively reduce the emission of carbon dioxide gas and its impact on global of climate change.At present,hydrogen energy has become one of the energy sources for human society to achieve sustainable development,so it has attracted much attention.The main task of this paper is to synthesize catalysts and prepare hydrogen by electrocatalysis and photocatalysis.The work of paper includes five sections:1)A new kind of material for both coupling copper complex.[Cu₂?L?₂]1 is formed by the reaction of CuCl₂.2H₂O with a tetra-dentate ligand,6-?3-aminomethylpropanol?-2-tert-buty-4-methylphenol?H₂L?,which is prepared by a reaction of 2-tert-butyl-4-methylphenol,3-amino-1-propanol,and formaldehyde,its electrocatalytic hydrogen production properties are studied.2)A novel cobalt complex[?phen?₂Co?CN?₂].NO₃ 2 was synthesized from1,10-phenanthroline,Co?NO₃?₂.6H₂O and tetracyanoethylene?TCNE?.The study found that the complex is soluble in water and has the ability to electrocatalytically produce hydrogen.3)synthesis of a new kind of water soluble catalyst based on a coordinatively saturated cobalt complex,[?phen?₂Co?CN?₂].ClO₄ 3 that is formed by the reaction of1,10-phenanthroline?phen?,Co?ClO₄?₂.6H₂O and tetracyanoethylene?TCNE?.I study the cobalt complex of electrocatalytic hydrogen production and photocatalytic hydrogen production.4)Searching the literature for the synthesis of a nickel complex of known structure[BzPyN?CH₃?₂]₂[Ni?mnt?₂]4 and the ligand mnt^2-=maleonitriledithiolate.The CdS nanorods were selected as photosensitizers and studied in multiphase.Photocatalytic performance of hydrogen production.5)Searching the literature for the synthesis of a nickel complex of known structure[BzPyN?CH₃?₂]₂[Ni?i-mnt?₂]5(i-mnt^2-=2,2-dicyanoethylene-1,1-dithiolate)that acts as both an electrocatalyst and a photocatalyst for H₂ generation from water.electrocatalytic hydrogen production is homogeneous,photocatalytic hydrogen production of multiple phases.
