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.

通过环境友好的软化学过程成功合成了出色的长波长度可见光诱导的光催化剂。含有可见光诱导的光催化剂的复合材料在较长的余辉磷在紫外线/粘膜/室内光照射下以及关闭光线后持续的活性表现出极好的光催化活性。一个有希望的策略涉及建立可见光的光响应光催化剂与长余辉磷酸的耦合。对于光催化剂的合成而言，这是一个新概念，这意味着新型的全日制活性光催化系统的可能性。
