Metal-Organic Frameworks: Preparations and Applications of Highly Efficient Heterogeneous Photocatalysis
Metal-organic frameworks (MOFs) attract considerable attention due to tuneable structures, tailorable functionalities, and replaceable metal centers, leading to comprehensive applications, such as semiconductors, catalysts, and photocatalysts. Herein, basic concepts and overall synthetical technologies of MOFs and MOF-derived materials are introduced, such as solvothermal, hydrothermal, microwave-assisted, sonochemical, mechanochemical, and electrochemical methods. MOFs can provide an orderly porous structure, which will contribute to the high exposure of active sites and hence promote the photocatalytic performance efficiently. In this paper, the applications of MOFs for the photocatalytic reactions focally on water splitting mainly and other possible utilizations, including CO2 reduction and oxidative degradation, are summarized. It gives a concise review of recent progress on MOFs and MOF-derived materials for photocatalysis. A summary and prospect for MOFs to conduct the photocatalysis are also highlighted.
