Progress in noble metal/MOFs nanocomposite structure materials and their applications

Metal-organic frameworks (MOFs) have attracted much attention due to their large specific surface area, high porosity, easy modification, large number of active sites and porous structures, and have been widely used in many fields, such as gas storage, sensors, catalysts and other fields. However, due to its inherent defects, their further practical applications in the above fields have been limited. Noble metal nanomaterials have excellent electrical conductivity, good catalysis and unique localized surface plasmon resonance (LSPR) effect. Therefore, researchers have delicately constructed nanocomposite structural materials by combining noble metal nanomaterials and MOFs in various forms in recent years. Due to the synergistic effect of the two, a series of novel characteristics have been generated, enriching the application fields of MOFs materials and significantly improving their performance. In this paper, the application progress of Au, Ag, Pt and other noble metal/MOFs nanocomposite structural materials in catalysis, sensing, biomedicine and hydrogen storage in recent years is reviewed, which provides new ideas for preparing new nanocomposite materials and exploring new applications.
