Preparation of Quantum Dots @ Metal-Organic Frameworks and Its Application in the Field of Photocatalytic Degradation

Metal-organic frameworks (MOFs) materials have attracted much attention in the field of photocatalysis, as compared with conventional porous materials, which are structurally ordered and diverse, with adjustable pore size and ultra-high specific surface area. At the same time, quantum dots (Quantum Dots, QDs) of nano-fluorescent materials have good optical properties and can convert near-infrared light into visible light, which can promote the absorption of visible light, which accounts for a large proportion of the solar spectrum, and the emergence of QDs has also contributed to the development of photocatalysis. But as a single phase catalyst, they have autologous shortcomings, limiting their use as a photocatalyst for future application and development. In recent years, researchers have found that the effective combination of QDs and MOFs materials to form a composite photocatalyst is one of the ways to improve the photocatalytic performance of single phase catalysts, and a preliminary study has been carried out. The results show that catalytic performance is greatly improved and it has broad application prospect in solving environmental problems. This paper combines the status quo at home and abroad, and a series of studies on the preparation of QDs@ MOFs composite photocatalyst as well as its application and development in the field of photocatalytic degradation are reviewed. This paper also puts forward the key problems that should be paid attention to in the process of QDs @ MOFs composite photocatalyst and the future development trend.
