Disclosed herein are metal-organic frameworks and methods of making and use thereof.

A visible light-reactive photocatalyst includes: a metal-organic framework (MOF) including pores; and an active material doped on the surface of the metal-organic framework, wherein the active material includes molybdenum disulfide (MoS.sub.2) or titanium oxide (TiO.sub.2).

A nanocatalyst for partial oxidation of methane is disclosed. The nanocatalyst is prepared by carbonizing a metal-organic framework coordinated with copper ions to form a structure in which nitrogen atoms present in a nitrogen-doped porous carbon structure form coordinate bonds with copper ions. This structure enhances the chemical stability of the nanocatalyst, prevents the peroxidation of methane at low temperature, and significantly improves the conversion efficiency of methane to liquid products such as methanol and methyl hydroperoxide by selective partial oxidation of methane gas. Also disclosed are a method for preparing the nanocatalyst and a method for partial oxidation of methane using the nanocatalyst.

Described herein is a catalytic reaction process including introducing one or more gas-phase reactants into a reactor comprising a microporous catalyst having a pore size less than or equal to 2 nm and adjusting the temperature and/or the pressure of the reactor such that one or more of the gas-phase reactants condense within the micropores of the catalyst thereby causing the catalytic reaction to take place in a liquid phase. Additionally, a process for engineering defects on a carboxylate-based metal organic framework (MOF) catalyst is described. The process includes providing a carboxylate-based MOF catalyst; and heating the carboxylate-based MOF catalyst in an inert gas atmosphere at temperatures between about 150° C. and about 900° C.

The disclosure provides for zirconium terephthalate-based metal organic frameworks with open metal sites, and uses thereof.

A metal-organic framework (MOF) MIL-125 and a preparation method and a use thereof are provided. The MOF MIL-125 is a round cake-like crystal and has an external specific surface area (SSA) of 160 m.sup.2/g to 220 m.sup.2/g. The MOF MIL-125 provided in the present application has a large number of microporous structures, a large external SSA, and a high catalytic activity in oxidation.

The disclosure is related to the field of preparation of nanometer materials, and, in particular, to a method for synthesizing a 2D ultrathin zeolitic imidazolate framework-67 (ZIF-67) with a hierarchical porous structure, the method converting ZIF-67 from nanoparticles into 2D ultrathin nanosheets with a hierarchical porous structure by controlling a dropping amount of water and the reaction time. With the method, the 2D ultrathin ZIF-67 with a hierarchical porous structure can be made from readily available starting materials in a one pot synthesis. The method is feasible on industrial scale and has both economic and environmental benefits due to the simple process and low cost.

Cyclic peptides including the amino acid sequence selected from SEQ ID NO:1-6, multimers thereof, and metal organic frameworks including the cyclic peptides or multimers thereof are provided.

An MOFs/MIPs catalyst, an in situ growth preparation method for same, and applications thereof are provided. The method comprises: uniformly mixing template molecules, a functional monomer, and a pore-foaming agent and performing a prepolymerization to produce a prepolymerization reaction product; uniformly mixing a cross-linking agent, an initiator, and the prepolymerization reaction product, heating, eluting the template molecules via a Soxhlet extraction, and drying to produce an imprinted polymer; uniformly mixing dimethylformamide, 2,5-dihydroxyterephthalic acid, ferrous chloride, water, methanol, and the imprinted polymer, heating, washing, using methanol for immersion and washing, and drying to produce the MOFs/MIPs catalyst.

A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more MOF catalysts, which may be prepared from a precursor metal-organic framework (MOF). A MOF catalyst may be prepared by exchanging one or more organic linking ligands of the precursor MOF for an organic linking ligand having a different acidity and/or electron-withdrawing properties, which, in turn, may affect catalytic activity.
