摘　　要：电解水制氢是一项高效的大规模制氢技术,它涉及两个半反应:一个是阳极反应(OER),另一个是阴极反应(HER).目前,研究高效、低成本的OER催化剂可以更好地实现水的高效全分解.以1,3,5-苯三甲酸为配体,过渡金属Cu(Ⅱ)离子为中心原子,通过水热法合成了Cu-MOFs.然后高温热解,得到了一系列Cu@C-X催化剂材料,并将其应用于电解水反应(OER)中,通过测定其循环伏安曲线和LSV曲线,表明在600℃煅烧温度时得到的材料Cu@C-600是活性和稳定性最好的催化剂.Hydrogen production by electrolysis of water is an efficient large-scale hydrogen production technology,which involves two half reactions,one is anode reaction(OER)and the other is cathodic reaction(HER).Currently,the study of high efficiency and low cost OER catalysts can better achieve efficient full decomposition of water.Cu-MOFs were synthesized by hydrothermal method using 1,3,5-phthalic acid as ligand and transition metal Cu(Ⅱ)ions as central atoms.And then high-temperature pyrolysis was carried out to obtain a series of Cu@Cu@C-X catalyst materials,which were applied to the water electrolytic reaction(OER).By measuring the cyclic voltammetric curve and LSV curve,Cu@C-600 obtained at a calcination temperature of 600℃is the catalyst with the best activity and stability.
