银负载金属有机骨架复合材料的制备及应用进展

Progress in preparation and application of silver-loaded metal-organic framework composites

金属有机骨架(MOFs)材料因比表面积大、孔隙率高、结构可调及生物相容性好等诸多优势而具有广阔的应用前景。银纳米粒子(Ag NPs)具有优异的抗菌、催化及光电性能,但在合成过程中易发生团聚而导致性能降低。MOFs丰富的孔隙结构能够起到分散和固定Ag NPs的作用,MOFs材料可与Ag NPs协同作用,从而提高和拓宽银负载金属有机骨架(Ag@MOFs)复合材料的性能和应用领域。归纳了不同种类及形貌的Ag@MOFs复合材料,综述了Ag@MOFs复合材料的合成方法以及在抗菌、催化及传感检测领域中的研究进展,指出了该复合材料面临的挑战并展望了其未来发展前景。

Metal-organic frameworks(MOFs)have broad application prospects due to their large surface area,high porosity,adjustable structure and good biocompatibility.Silver nanoparticles(Ag NPs)have excellent antibacterial,catalytic and photoelectric properties,but they are prone to agglomeration in the synthesis process,resulting in degradation of performance.The rich pore structure of MOFs can play a role in dispersing and fixing Ag NPs.MOFs materials can form a synergistic effect with Ag NPs,thereby improving and broadening the performance and application fields of Ag@MOFs composites.Ag@MOFs composites with different types and morphologies were summarized,and the synthesis methods of Ag@MOFs composites were further reviewed.The latest research progress and prospects of Ag@MOFs composites in the fields of antibacterial,catalytic and sensing detection were discussed.
