Abstract: Multicomponent nanoparticles include two or more dissimilar components selected from different members of 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 polyfunctional dispersing agent such that the multicomponent nanoparticles have a substantially uniform distribution of the two or more dissimilar components. The polyfunctional dispersing agent may include organic molecules, polymers, oligomers, or salts of these. The molecules of the dispersing agent bind to the dissimilar components to overcome same-component attraction, thereby allowing the dissimilar components to form multicomponent nanoparticles. Dissimilar components such as iron and platinum can be alloyed together using the dispersing agent to form substantially uniform multicomponent nanoparticles, which can be used alone or with a support. At least a portion of the dispersing agent is removed by reduction and/or oxidation.

Abstract: Organically complexed nanocatalyst compositions are applied to or mixed with a carbon-containing fuel (e.g., tobacco, coal, briquetted charcoal, biomass, or a liquid hydrocarbon like fuel oils or gasoline) in order to enhance combustion properties of the fuel. 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. In addition, coal can be treated with inventive nanocatalyst compositions to reduce the amount of NOx produced during combustion (e.g., by removing coal nitrogen in a low oxygen pre-combustion zone of a low NOx burner). 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.

Abstract: An improved catalytic process for producing hydrogen peroxide directly by reaction of hydrogen and oxygen is disclosed. The process employs staged or sequential feeding of portions of the hydrogen feedstream into zones in the catalytic reactor in amounts sufficient to maintain an essentially constant and preferred ratio of oxygen to hydrogen at the inlet to each of the vessel's zones whereby high selectivity for hydrogen peroxide production is achieved and excess oxygen recycle requirements are minimized.

Abstract: A noble metal nanometer-sized catalyst composition is described along with the method for preparation of the composition. The crystal face of the catalyst contains a preponderance of (111) type crystal phase exposure. The crystal phase exposure is controlled by sequestering the noble metal cation before deposition on a catalyst support. Controlled catalyst face exposition combined with the nanometer scale of the catalyst increases the catalyst selectivity and activity, particularly for hydrogenation and dehydrogenation reactions.

Abstract: Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.
