摘要

A feasible process called as the hydrogen evolution of water electrolysis assisted by photocatalysis (WEAP) was proposed and experimentally achieved. In comparison with traditional alkaline electrolytic cell for water electrolysis with Ni anode, H-2-production rate increased by 118% and the applied direct voltage reduced by 14.5% in WEAP with photoactive Ni anode modified by TiO2 nanotubes.
