Advantages of Bimetallic Organic Frameworks in the Adsorption, Catalysis and Detection for Water Contaminants

Abstract

The binary metal organic framework (MOF) is composed of two heterometallic ions bonded to an organic ligand. Compared with monometallic MOFs, bimetallic MOFs have greatly improved in terms of structure, porosity, active site, adsorption, selectivity, and stability, which has attracted wide attention. At present, many effective strategies have been designed for the synthesis of bimetallic MOF-based nanomaterials with specific morphology, structure, and function. The results show that bimetallic MOF-based nanocomposites could achieve multiple synergistic effects, which will greatly improve their research in the fields of adsorption, catalysis, energy storage, sensing, and so on. In this review, the main preparation methods of bimetallic MOFs-based materials are summarized, with emphasis on their applications in adsorption, catalysis, and detection of target pollutants in water environments, and perspectives on the future development of bimetallic MOFs-based nanomaterials in the field of water are presented.

[15d] In contrast to other methods, the one-pot synthesis approach allows for the simple room-temperature mixing of raw materials to obtain the product.…”

Metal-Node-Engineered MOF-Derived Cobalt Manganese Selenide with Synergetic Surface Tailoring for Energy Storage Applications

“…Instead of using single metal nodes, bimetal nodes are more advantageous as they offer binuclear metal clusters since the synergetic effect between the metal nodes of two different metals can dictate the conductivity of the MOFs . Therefore, a second metal is introduced in the MOF with the intention of improving the electrochemical properties of the parent MOF without damaging the inherent advantages of the parent MOF, in addition to achieving meritorious morphology. , The combined effect of bimetal nodes is realized with the synergetic effect at the interface, arising from the heterojunction formed. − The surface state and electronic configuration of the bimetal centers are determined by the synergetic effect of the bimetal nodes. So, the combination of two metal nodes and their uniform distribution boost the electronic coupling, which is reflected in the electrochemical properties …”
