  • Patent number: 9689085
    Abstract: A method of depositing contiguous, conformal submonolayer-to-multilayer thin films with atomic-level control is described. The process involves electrochemically exchanging a mediating element on a substrate with a noble metal film by alternatingly sweeping potential in forward and reverse directions for a predetermined number of times in an electrochemical cell. By cycling the applied voltage between the bulk deposition potential for the mediating element and the material to be deposited, repeated desorption/adsorption of the mediating element during each potential cycle can be used to precisely control film growth on a layer-by-layer basis.

    Abstract: The present invention concerns a method of preparation of nanoparticular metal oxide catalysts having a narrow particle size distribution. In particular, the invention concerns preparation of nanoparticular metal oxide catalyst precursors comprising combustible crystallization seeds upon which the catalyst metal oxide is co-precipitated with the carrier metal oxide, which crystallization seeds are removed by combustion in a final calcining step. The present invention also concerns processes wherein the nanoparticular metal oxide catalysts of the invention are used, such as SCR (deNOx) reactions of nitrogen oxides with ammonia or urea as reductant, oxidations of alcohols or aldehydes with dioxygen or air to provide aldehydes, ketones or carboxylic acids, and photocatalytic oxidation of volatile organic compounds (VOCs).

  • Patent number: 8946113
    Abstract: The present invention relates to an Fe-modified perovskite-type catalyst, a method for preparing same and a method for preparing a synthesis gas by a combined reforming reaction using same. More particularly, it relates to a catalyst for a combined natural gas/steam/carbon dioxide reforming reaction having a perovskite structure with La and Sr introduced at the A site and Ni and Fe introduced at the B site with specific molar ratios and a method for producing a synthesis gas for Fischer-Tropsch synthesis or methanol synthesis using the catalyst by the combined reforming reaction. The catalyst of the present invention exhibits higher carbon dioxide conversion rate, significantly reduced catalyst deactivation caused by carbon deposition and improved long-term catalyst stability and activity, as compared to the existing catalyst for reforming reaction prepared by the impregnation method.
