摘要：
Photocatalysis activated by visible light remains highly challenging. Here, we report novel MoSe2/ZnO/ZnSe (ZM) hybrids fabricated via a simple hydrothermal method for photocatalytic reduction of Cr(VI) under visible light irradiation. ZM hybrids show improved photocatalytic reduction ability under visible light irradiation compared to pure ZnO owing to good visible light absorption and rapid electron transfer and separation. The ZM hybrid shows the highest Cr(VI) reduction rate of 100%. Moreover, the photocatalytic Cr(VI) reduction process is mainly controlled by photoinduced electrons.
