Research status of preparation and photocatalysis of zinc ferrite

To improve the catalytic efficiency of zinc ferrite, the specific surface area is increased, and the surface morphology of zinc ferrite is optimized. Besides, the zinc ferrite is combined with other materials to obtain more efficient and practical photocatalyst. The modification methods of zinc ferrite and the preparation methods of zinc ferrite with different morphologies were analyzed and summarized in this paper, and the particle size unevenness after the modification and the research direction were briefly discussed and prospected. The zinc ferrite combined with other materials can prepare the composite photocatalyst with high activity and stable performance, which can improve the catalytic ability of the composites and alleviate the problem of low catalytic activity of zinc ferrite. The preparation of zinc ferrite with different morphologies can increase the specific surface area of zinc ferrite, improving the catalytic efficiency of zinc ferrite.
