Abstract: A method of forming TiO2—ZnO nanoparticles coated by a copper (II) complex includes forming a mononuclear copper complex by treating a ligand with Cu2+ ions; and immobilizing the mononuclear copper complex on TiO2—ZnO nanoparticles to obtain the TiO2—ZnO nanoparticle coated by the copper (II) complex. The TiO2—ZnO nanoparticles coated by a copper (II) complex thus produced have improved catalytic effectiveness and increased efficiency by reducing catalytic reaction time and temperature, particularly in methods of catalyzing oxidation of an alcohol or of catalyzing decarboxylative bromination of an acid.

The reactant may further include water in the form of steam. The reactant is introduced to a perovskite catalyst in the reactor. The perovskite catalyst promotes the formation of the higher carbon compounds from ethanol, and may be in the form of a powder or thin film. The perovskite catalyst has the formula ABO3, wherein A is one or more selected from a group consisting of La and Sr, and wherein B is one or more selected from a group consisting of Mn, Ca, Fe, and Co. The perovskite catalyst particularly may be La0.7Sr0.3MnO3. The obtained higher carbon compounds may include at least one of acetone and crotonaldehyde.

Abstract: Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed, and these processes include the steps of forming a supported chromium catalyst comprising chromium in a hexavalent oxidation state, irradiating the hydrocarbon reactant and the supported chromium catalyst with a light beam at a wavelength in the UV-visible spectrum to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the alcohol compound and/or the carbonyl compound. The supported chromium catalyst can be formed by heat treating a supported chromium precursor, contacting a chromium precursor with a solid support while heat treating, or heat treating a solid support and then contacting a chromium precursor with the solid support.

Abstract: The present invention relates to the field of catalysts, and provides a porous layered transition metal dichalcogenide (TMD) and a preparation method and use thereof. The preparation method includes the following steps: (1) mixing silica microspheres, a transition metal salt and an elemental chalcogen, and pressing to obtain a tablet, the silica microspheres having a same or different particle diameters; and (2) sintering the tablet under hydrogen, and removing the silica microspheres to obtain the porous layered TMD. The porous layered TMD prepared by the method of the present invention has a high lattice edge exposure, which provides more active sites and higher catalytic activity, so the porous layered TMD can effectively catalyze the oxidation of alcohols to aldehydes or sulfides to sulfoxides under visible light irradiation.

Abstract: The present invention provides modified cycloalkyne compounds; and method of use of such compounds in modifying biomolecules. The present invention features a cycloaddition reaction that can be carried out under physiological conditions. In general, the invention involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).

Abstract: Processes for converting an olefin reactant into a diol compound are disclosed, and these processes include the steps of contacting the olefin reactant and a supported chromium catalyst comprising chromium in a hexavalent oxidation state to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the diol compound. While being contacted, the olefin reactant and the supported chromium catalyst can be irradiated with a light beam at a wavelength in the UV-visible spectrum. Optionally, these processes can further comprise a step of calcining at least a portion of the reduced chromium catalyst to regenerate the supported chromium catalyst.
