摘要：

Developing a highly efficient water-splitting photocatalyst for hydrogen production under visible light is urgent. In this study, beta-SiC nanowire photocatalysts loaded with 0.01-0.1 wt. % nickel were prepared. Their microstructure and hydrogen production activity were studied. The catalyst with 0.05 wt. % nickel and a sacrificial agent Na2S-Na2SO3 shows the highest hydrogen production rate of 375.4 mu mol g(-1) h(-1) since the loaded nickel prohibits the recombination of photogenerated electron-hole pairs in the system, which enhances the photocatalytic activity.
