摘要

采用层层组装的方法在Ni片阳极上分别组装TiO2/ZnO纳米棒阵列(TiO2/ZnONRs)和TiO2纳米管阵列(TiO2NTs)。以碱性电解池为基础，采用紫外线辐照阳极，将光催化与电解水有机地耦合在一起，提出并实现了光催化辅助电解水制氢的新过程。通过FE-SEM、XRD、EDS、UV-Vis和光催化辅助电解水制氢(WEAP)等方法，对修饰电极的结构和性能进行了表征和测试。结果表明，TiO2/ZnONRs比TiO2NTs修饰Ni阳极的光催化辅助电解水产氢速率快。TiO2/ZnONRs和TiO2NTs修饰Ni电极比纯Ni片作阳极的WEAP过程产氢速率分别提高了1.75和1.50倍。电耗分别降低了约10.5%和9.0%。

Abstract

TiO2/ZnO nanorode arrays (TiO2/ZnONRs)and TiO2 nanotube arrays (TiO2NTs)were assembled on Ni substrate anodes by the layer by layer (LBL)process.The anode of an alkaline electrolytic cell for water electrolysis was irradiated by ultraviolet light.The water electrolysis process was coupled with photocatalytic decomposition of water for hydrogen preparation.A new process for hydrogen preparation of water electrolysis assisted by photocatalysis (WEAP)was proposed and experimentally confirmed.FE-SEM

XRD

EDS，UV-Vis and WEAP measurement were used to characterize the structure and performance of modified Ni anode.The rate of hydrogen evolution in WEAP of modified Ni anode with TiO2/ZnONRs was higher than that with TiO2NTs.Comparing to sole Ni anode

the rate of hydrogen evolution of TiO2/ZnONRs and TiO2NTs modified Ni anode was increased by 1.75 and 1.50 times respectively.And the consumption of electric power was decreased by 10.5% and 9.0% respectively.
