Research Progress of Zinc Ferrite as Photocatalyst

Zinc ferrite is a n-type semiconductor with high photocatalytic activity and visible light sensitive, the unique magnetic properties and chemical stability make it widely used in the field of photocatalysis. For various morphology of zinc ferrite, different modification methods can be taken to make it more efficient and practical. In recent years, taking advantage of the zinc ferrite characteristics, the preparation of magnetic recovery and stable performance of the composite photocatalyst has attracted the attention of researchers. In this paper, the basic properties of zinc ferrite as photocatalyst and the preparation methods of various morphology are introduced. The modification technology and modification mechanism of zinc ferrite in photocatalysis are discussed. At the same time, the existing problems and prospects are pointed out.
