Promotional effect of Rh nanoparticles on WO3/TiO2 titanate nanotube photocatalysts for boosted hydrogen production
Abstract
Titanate nanotubes were synthesized by microwave irradiation. Rhodium nanoparticles were loaded on WO3/NT photocatalysts. Rh-WO3/NT shows remarkably photocatalytic activity under UV light and visible light. Rh acts as co-catalyst of WO3/NT, while WO3 stabilizes the structure of nanotubes. The diagram of density of states (VB and CB) can be determined from UV–vis and XPS.
