Preparation of ma ic composite photocatalyst Fe O /SiO /Bi WO 3 4 2 2 6 and its photocatalytic activity Reporter：Wu Huating Supervisor ： Ding Xingeng Contents 1 Background and objectives 2 Research contents 3 Conclusion 1. Background 2n+ (Bi O ) 2 2 n (WO ) 2n− 4 n ➢ Semiconductor photocatalysis can be used to pose various orgenergyanic compounds in open air under aqueous conditions with solar. ➢ Bismuth tungstate (Bi2WO6), one of the simplest Aurivillius phase oxides, has been used as a new photocatalyst that works under visible light irradiation. ➢ However, it is not easy to reuse the photocatalyst due to difficulty in its recovery from the reaction media. 1. Objectives Ma Ma ic Organic Absorption Separation photocatalyst compounds degradation Recycle ➢Improve photocatalytic activity ➢Improve stability and reusability 2. Research contents 1. Shape evolution of Bi WO micro/nano-structures
