摘要

半导体光催化材料的微观形貌及晶面控制是目前光催化研究领域的热点问题。Ag3PO4的光量子效率高、光氧化能力强,是一种能吸收可见光的新型光催化材料。综述了Ag3PO4光催化材料在微观形貌构建和晶面效应研究方面的现状、进展及存在的问题。目前,在微观形貌构建方面已经合成了具有纳米尺寸、空心结构、多孔结构、二维树枝结构、一维空心多孔结构及其他微观结构的Ag3PO4材料,极大地提高了光催化活性,后期需要进一步优化微观结构和颗粒尺寸并开发新型微观结构以获得性能更好的光催化材料;在晶面调控方面,合成了暴露不同指数晶面的Ag3PO4材料,后期需要在机理研究、合成方法及不同晶面的协同效应方面进行优化设计以获得更高的性能。探究了微观形态与光催化性能之间的构效关系,为设计和构建高效稳定的Ag3PO4光催化材料提供了一定的理论依据和研究思路。

Abstract

The morphology and crystal surface control of semiconductor photocatalysts are research focus in the photocatalysis area.Ag3PO4 as a new visible light photocatalyst is possessed of high photoquantum efficiency and strong photooxidation ability.The current status,research progress and existing problems in the microstructure construction and crystal surface effect of Ag3PO4 photocatalysts were reviewed.In terms of microstructure construction,Ag3PO4 materials with nano-size,hollow structure,porous structure,two-dimensional dendritic structure,one-dimensional hollow porous structure and other microstructure were synthesized,which greatly improved the photocatalytic activity.It was necessary to further optimize the relationship between microstructure and particle size,as well as develop new microstructure to obtain better photocatalytic materials.In terms of crystal surface regulation,Ag3PO4 materials exposed to different exponential crystal surfaces were synthesized,which required optimization design in terms of theoretical research,synthesis method,and synergistic effect of different crystal surfaces to obtain higher performance.The structure-activity relationship between microscopic morphology and photocatalytic performance was explored,which provided certain theoretical basis and research ideas for the design and construction of efficient and stable Ag3PO4 photocatalysts.
