摘　　要：钙钛矿量子点(Perovskite quantum Dots,PVK QDs)具有可见光响应强度高、发光纯度高以及量子效率高等优点,在光电领域有广阔的运用前景,但其晶体结构在光、热、水、氧存在的条件下稳定性较差;金属有机框架(Metal organic frameworks,MOFs)是一种比表面积大、孔道结构可调的多孔材料,具有较高的环境稳定性。通过将钙钛矿量子点嵌入金属有机框架的孔道中,既能提高钙钛矿量子点的稳定性,又赋予MOFs优异的光学性能。本文综述了近年来钙钛矿量子点与金属有机框架复合材料的研究进展,总结出了4种主要的合成方法:模板法、原位生长法、后合成法和机械化学法,并比较了这些制备方法的优缺点;此外,从应用的角度讨论了复合材料在太阳能电池、LED领域、二氧化碳还原(CO_2RR)以及污水处理、信息加密等领域的工作机理。最后,文章分析并展望了绿色机械化学法制备钙钛矿量子点与金属有机框架复合材料的产业化前景以及复合材料在实际应用中所面临的亟待解决的问题。Perovskite quantum dots(PVK QDs)have the advantages of high visible light response intensity,luminescence purity and quantum efficiency,which have broad application prospects in the field of optoelectronics.But its crystal structure is vulnerable under the existence of light,heat,water,and oxygen.Metal organic frameworks(MOFs)are porous material with large specific surface area and adjustable pore structure,which have high environmental stability.By embedding perovskite quantum dots into the channels of the metal organic frameworks,the stability of perovskite quantum dots and the optical properties of MOFs can be improved at the same time.In this paper,four main synthesis methods of perovskite quantum dots and metal organic framework composites in recent years have been reviewed,including the template method,in⁃situ growth method,post synthesis method,and mechanochemical method.And the advantages and disadvantages of these preparation methods are compared.In addition,the working mechanism of composite materials in the fields of solar cells,LEDs,carbon dioxide reduction(CO_(2)RR),sewage treatment,and information encryption are discussed from the perspective of application.Finally,the industrialization prospect of perovs⁃kite quantum dots and metal organic framework composites prepared by green mechanochemical method and the problems to be solved in the practical application of the composites are analyzed and prospected.
