Abstract: Provided herein is a novel silica-supported nickel nanocomposite and a novel one-pot solution combustion synthesis of that nanocomposite. The method allows the synthesis of small size nickel nanoparticles (e.g., 3 nm to 40 nm) for which a considerable percentage of nickel is inserted into silica, experiencing strong metal-support interaction. These exceptional physicochemical properties make them desirable for various industrial applications, such as electronic, heterogeneous catalysis as well as conversion and storage of energy.

Abstract: The present invention relates to a method for preparing, activating and regenerating a metal supported catalyst, comprising: treating a Ma-Mb-Mc metal supported catalyst at 10-700° C. by using an ammonia or nitrogen-containing organic matter, wherein the Ma metal is an active metal selected from one or more of a noble metal atom or a transition metal, the support is a common industrial porous catalyst, and the Ma metal is dispersed on the support in a state of single atomic site. According to the Md-Mb-Mc metal supported noble metal/zinc catalyst treated by the method of the present invention, the direct dehydrogenation conversion rate and selectivity of catalyzing light alkanes are remarkably improved; the method for preparing the catalyst is simple in process, the catalytic activity after regeneration is still kept, and the catalyst can be industrially produced on a large scale.

Abstract: Supported catalysts contain a transition metal compound impregnated on or bound to a solid support, and the transition metal is iron, cobalt, or manganese. The solid support is an inorganic solid oxide or a chemically-treated solid oxide. The transition metal compound is prepared by reacting a transition metal halide containing a ligand with an alkylating agent in a suitable reaction medium at a temperature of −70 to 15° C., prior to impregnating onto the solid support.

Abstract: A method for the selective cleavage of a compound comprising an aromatic ring and a C—O—C linkage in the presence of a heterogeneous catalyst is provided. The heterogenous catalyst may be a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.

Abstract: Disclosed is a catalyst based on synthetic silica, in a heterogeneous catalysis method, to promote the effective conversion of residual glycerin, resulting from the production of biodiesel, into formic acid with high selectivity and stability, in a continuous flow reaction. The conversion of residual glycerin occurs by homogeneous catalysis, by the action of components remaining from the synthesis of biodiesel, with the formation of major compounds, such as formic acid, cyclic ethers and diglycerol, in continuous flow and reflow reactions. The reaction can also be carried out by adding sodium salts in the homogeneous catalytic conversion process of commercial glycerin. The process values the residual glycerin, without the need for purification before its transformation into products with high added value, but of renewable origin, adding more interest and potential.

Abstract: Claimed herein is a method of applying amorphous Co—SiOx to activate PMS and produce SO4·− due to the formation of Co(II)-Ov, pairs via the substitution of Si by Co. The inherent Co significantly change the electronic structure of O and Si atoms in the Co—SiOx via final state effects and increase the conductivity in terms of more effective electron transfers. The claimed method using Co—SiOx functions as a more effective oxidative catalyst for the faster degradation of pollutants. The simplicity of the synthetic procedures indicates that the conductive Co—SiOx could be used for the activation of PMS and other electrochemical applications on a wider scale.
