| Research Abstract |
Excellent long-wavelength visible light induced photocatalysts were successfully synthesized by an environmental friendly soft-chemical process. The composites containing visible light induced photocatalysts loaded on long afterglow phosphor displayed excellent photocatalytic activity under UV-light/Vis-light/indoor light irradiation as well as persistent activity after turning off light. A promising strategy involves coupling of visible light responsive photocatalyst with long afterglow phosphor was established. It is a new concept for the photocatalyst synthesis implying a possibility of a novel persistent full-time active photocatalytic system.
