摘要： Supported reactive catalysts having a controlled coordination structure and methods for their production are disclosed. The supported catalyst comprises catalyst particles having top or outer layer of atoms in which at least a portion of the atoms exhibit a controlled coordination number of 2. Such catalysts may be manufactured from intermediate precursor compositions that include a control agent in which a preponderance of the molecules are straight-chained rather than branched. The supported catalysts of the present invention are useful for the preparation of hydrogen peroxide with high selectivity in addition to other chemical conversion reactions. The catalyst and methods may be used for the concurrent in situ and ex situ conversion of organic compounds. In addition, a process is provided for catalytically producing hydrogen peroxide from hydrogen and oxygen feeds by contacting them with the catalysts of the invention and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14 x 10 -4 and 5.0 x 10 -4 .

摘要： Organically complexed nanocatalyst compositions are applied to or mixed with a carbon-containing fuel ( e.g. , coal, briquetted charcoal, tobacco, biomass, or a liquid hydrocarbon like fuel oils or gasoline) in order to enhance combustion properties of the fuel. The nanocatalyst compositions include nanocatalyst particles made using a dispersing agent. They can be formed as a stable suspension to facilitate storage, transportation and application of the catalyst nanoparticles to a fuel substrate. Nanocatalyst compositions can be applied to or mixed with a solid fuel substrate in order to reduce the amount of CO, hydrocarbons and soot produced by the fuel during combustion, hi addition, a nanocatalyst composition can be applied to or mixed with coal prior to or upon introducing the coal into a coal burner in order to catalyze the removal of coal nitrogen from the coal and its conversion into nitrogen gas prior to combustion of the coal. This leads to reduced NOx production during coal combustion.

摘要： Nanoparticles include a plurality of two or more dissimilar components selected from the group of noble metals, base transition metals, alkali earth metals, and rare earth metals and/or different groups of the periodic table of elements. The two or more dissimilar components are dispersed using a dispersing agent such that the nanoparticles have a substantially uniform distribution of the two or more dissimilar components. The dispersing agents can be poly functional small organic molecules, polymers, or oligomers, or salts of these. The molecules of the dispersing agent bind to the particle atoms to overcome same-component attractions, thereby allowing dissimilar components to form heterogeneous manoparticles. Dissimular components such as iron and platinum can be complexed using the dispersing agent to form sbstantially uniform heterogeneous nanoparticles. The nanoparticles can be used alone or applied to a support. At least a portion of the dispersing agent can be removed by reduction and/or oxidation.

摘要： Reforming nanocatalysts are formed using a dispersing agent to increase the activity, selectivity and longevity of the catalyst when used in a reforming process. The nanocatalyst particles are formed using a dispersing agent having at least one functional group selected from the group of a hydroxyl, a carboxyl, a carbonyl, an amide, an amine, a thiol, a sulfonic acid, sulfonyl halide, an acyl halide, an organometallic complex, and combinations of these. The dispersing agent is particularly useful for forming multicomponent catalysts comprising an alloy, combination, mixture, decoration, or interspersion of platinum and one or more of tin, rhenium or iridium. The formation of the nanoparticles may include a heat treating process performed in an inert or oxidative environment to maintain the catalyst atoms in a non-zero oxidation state to thereby maintain a stronger bond between the dispersing agent and the catalyst atoms. Multicomponent reforming catalysts having anchored nanocatalyst particles exhibit particularly good activity, selectivity and longevity when used in the reforming of naphtha and/or formation of BTX.
