摘要:

能源緊缺和環(huán)境污染是目前人類面臨的兩個嚴峻的問題，因此尋找和開發(fā)新型綠色能源成為當前研究的熱點之一。太陽能是一種綠色無污染并且可再生的能源，將太陽能轉換為有用的化學能是解決能源和環(huán)境問題的有效途徑之一。金屬有機框架材料(MOFs)是一類由金屬或金屬�惭鯁卧�通過有機配體連接形成的具有周期性網絡結構的三維多孔材料。MOFs不僅具有與分子篩類似的拓撲結構，而且其金屬�惭鯁卧�可以看做分立的半導體量子點，具有類似半導體的性質。因此，MOFs作為一類很有潛力的光催化材料吸引了廣大研究學者的注意，并已經在光解水產氫、污染物降解以及光催化有機合成等領域得到一些應用。其中，MOFs在光催化有機合成中的應用成為近幾年的研究熱點�？偨Y了MOFs材料在光催化氧化、CO2還原以及一些復雜的光誘導有機合成中的應用；同時以光還原CO2為模型反應，對提高MOFs光催化性能的方法進行了總結和分析，充分展示了MOFs基材料在光催化應用中的優(yōu)越性；最后，對MOFs在光催化有機合成中的應用前景進行了展望，強調了將MOFs的光催化特性與金屬/配體/客體分子等的催化性能結合，發(fā)展多功能的MOFs光催化材料的發(fā)展前景。

Abstract:

The ever increasing global demand for energy has stimulated a new wave of research activity on efficient utilization of solar energy. Photocatalysis is a promising pathway in the direct transformation of solar energy to chemical energy and has attracted increasing attention. Metal�瞣rganic frameworks (MOFs), which have both of the characteristics of semiconductor and zeolite, have emerged as a new kind of potential photocatalyst. After years of development, MOFs have been used in a variety of photocatalytic applications, such as hydrogen evolution, environmental remediation and organic transformations. Among these various applications, the use of MOFs in photocatalytic organic transformations has become the focus of current research. In this review, we summarized the recent progress towards the application of MOFs in photocatalytic organic transformations including CO2 reduction, redox reactions and some complex light�瞚nduced organic reactions like tandem reaction and C�睠 coupling reaction. New strategies to improve the photocatalytic efficiency of MOFs were illustrated. We also provided a detailed discussion on the development of MOFs as a kind of multifunctional photocatalysts. Finally, the existing problems and the opportunities as well as the challenges of MOFs in this field were also evaluated and anticipated.
