“…Metal–organic frameworks (MOFs), obtained from metal centers and organic ligands through coordination bonds, have received widespread attention in various frontier domains, such as proton conductivity, 1–5 ion fluorescence probes, 6,7 heterogeneous catalysts, 8–12 and gas separation and storage applications, 13–16 owing to their suitable size distribution, flexibility, high specific surface area, and good thermal stability. Particularly, MOFs are promising heterogeneous catalysts in green chemistry compared with homogeneous catalysts and traditional inorganic heterogeneous catalysts, 17,18 and have a series of advantages such as well-defined porosity, recyclability, and well-isolated catalytic sites.…”
