Photocatalysis technology has attracted much attention,since it is a potentially green technology to efficiently decompose organic dyes by utilizing solar energy.[1,2] Herein,Fe2O3/BiOCl photocatalysts are prepared by a facile hydrothermal method.Herein,Fe2O3 is selected as a coupling component with BiOCl on base of its following advantages: First,Fe2O3,is an abundant,low-cost and environmentally friendly chemical in nature,which is widely applied in magnetism,sensors and biologics and photocatalysis.21-27 Secondly,its energy bands can well match those of BiOCl,which favor for the transfers of photogenerated charges from one material to anaother.Thirdly,a stable heterojuction is easy to form between n-typed Fe2O3 and p-typed BiOCl semiconductors,which favors for the separation of photogenerated electrons and holes thus refrain effectively their recombination.
