摘　　要：制备以泡沫镍(NF)为基底的NiCo_(2)O_(4)/NF,并以此作为阳极,通过匹配商业化铂片析氢催化剂构建电化学方法处理污水耦合电解水制氢体系,评估NiCo_(2)O_(4)/NF阳极材料的电化学性能,考察体系的污水处理能力及运行情况。结果表明,采用一步水热法合成的NiCo_(2)O_(4)/NF具有低过电位及较好的稳定性;对体系施加3 V电压进行污水处理,96 h后COD和氨氮去除率分别达到44.1%和18.0%,并且降解COD和去除氨氮的反应与准一级反应动力学具有较高的相关性,在给定条件下具有相对较低的反应速率常数。NiCo_(2)O_(4)/NF阳极及其构建的电解水制氢同步污水处理体系实现了对污水的处理和净化,同时实现了氢气的制备。NiCo_(2)O_(4)/NF based on foam nickel(NF)was prepared and used as anode to construct a hydrogen produc-tion system coupled with sewage treatment by electrolyzing water through matching commercial platinum plate hy-drogen evolution catalyst.The electrochemical performance of NiCo_(2)O_(4)/NF anode material was evaluated,and the sewage treatment performance and operation of the system were investigated.The results indicated that NiCo_(2)O_(4)/NF synthesized by one-step hydrothermal method had low overpotential and good stability.Applying 3 V to the system and after 96 hours,the removal rates of COD and ammonia-nitrogen reached 44.1%and 18.0%,respectively.The degradation of COD and ammonia-nitrogen showed high correlations with the pseudo-first-order reaction kinetics and had relatively low reaction rate constants under given conditions.The NiCo_(2)O_(4)/NF electrocatalyst and its con-structed hydrogen production by water electrolysis synchronous sewage treatment system had realized the treatment and purification of sewage,as well as the production of hydrogen.
