摘　　要：作为一种功能性材料,金属有机框架材料(MOFs)具有独特的优点,如大比表面积、高孔隙率和可调控的形态形貌。然而,MOFs材料低劣的电子传输速率和低效的可见光收集能力限制了它的许多实际应用。MOFs衍生的多种金属基化合物可作为优良的导电介质,而获得的中空及多级孔隙性则能增强其多重光漫散射/反射效应,同时也可为高效复合其他能级匹配的光活性材料创造了条件。MOFs衍生得到原位形成的异质结架构能促进光电转换效率的大幅度提升。本文概述了光电化学传感器的原理,MOFs衍生物的制备方法及其结构特征,着重阐述了MOFs衍生的中空材料及其异质结复合物在光电生物传感器中的应用研究。同时也描述了Ⅱ型、p-n型等异质结材料及其在光电化学领域的性能研究。As a functional material,metal-organic framework materials(MOFs)have unique advantages,such as large specific surface area,high porosity and tunable morphology and shape.However,the poor electron transport rate and inefficient visible light harvesting ability of MOFs materials limit their practical applications.MOFs derived a variety of metal-based compounds can be used as excellent conductive media,while the obtained hollow and multilevel porosity enhances their multiplexed light diffuse scattering/reflecting effect,and also creates the conditions for efficiently compositing other energy-matched photo-reactive materials.MOFs-derivatives in situ formed heterojunction architectures can promote a substantial increase in the photoelectric conversion efficiency.This paper outlines the principles of photo-electrochemical(PEC)sensors,the preparation methods of MOFs derivatives with their structural features,and focuses on the application of MOFs-derived hollow materials and their heterojunction complexes in PEC biosensors.TheⅡtype,p-n type heterostructures and their performance studies in photoelectron-chemistry field are also described.
