摘要

Abstract

The photocatalytic activity of CdS can be greatly improved by co-modification of NiS and TiO

materials; furthermore the order of connection affects much. A directional electron transfer route via CdS → TiO

→ NiS is found crucial to the enhancement of ternary catalyst

where TiO

acts as an electron reservoir and NiS works as an effective cocatalyst. CdS/TiO

@NiS with NiS loaded on TiO

has an activity of H

evolution 2.5 times higher than NiS@CdS/TiO

with NiS pre-loaded on CdS. Faster e

separation rates is obtained of CdS/TiO

@NiS under visible light than under extra UV light irradiation

which in turn demonstrates the importance of directional electron transfer route.
