  • Patent number: 11369942
    Abstract: A method for assembling and synthesizing Cu2O particle-supported porous CuBTC includes the following steps of: 1) dissolving polyvinylpyrrolidone (PVP) in ethanol solution to obtain a PVP-ethanol solution; 2) dissolving copper salt in distilled water, and mixing with trimesic acid, salicylic acid, and the PVP-ethanol solution obtained in step 1) under stirring; and 3) conducting a hydrothermal reaction on the mixed solution obtained in step 2) at 120° C. to obtain Cu2O particle-supported porous CuBTC. The new method introduces salicylic acid during the synthesis of CuBTC. The salicylic acid, as a ligand precursor, forms a porous CuBTC material through the unsaturated coordination of a ligand under the catalysis of Cu ion. The resulting porous CuBTC supported with ultrafine Cu2O nanoparticles can adsorb high-energy molecules and exhibit excellent crystallinity, porosity, and stability.

  • Patent number: 11285456
    Abstract: This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has open coordination sites and has been post synthesis modified by partially occupying the open sites with a ligand such as acetonitrile (CH3CN). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.
