Abstract
Compared with monometallic metal-organic frameworks (MOFs) that are synthesized by reacting inorganic metal ions or clusters with bidentate or multidentate ligands via hydrothermal or solvothermal methods, the construction of heterogeneous frameworks like at least two kinds of metal sites in the individual nodes is proved to be an effective way to modulate their properties for advanced catalysis, especially for selective catalysis and multifunctional catalysis. However, it is still very challenging to precisely characterize their microstructures and reveal the relationship among the composition, structure, and their performances. Therefore, it is necessary to summarize the recent progress on bimetallic MOFs for thermal catalysis. First, we summarize the synthesis strategies and characterization methods of bimetallic MOFs and their derivatives. Second, the application of bimetallic MOFs and their derivatives as catalysts in thermal catalysis is discussed, and the relationship among the active components, structures, and their properties is elucidated. Third, the potential challenges and prospects of bimetallic MOF based nanocatalysts are proposed. This review will bring some insights into the design and preparation of bimetallic MOFs based nanocatalysts in the future.
