摘要： Titanium dioxide nanoparticles are formed using a dispersing agent to form nanoparticles with desired size, shape, and uniformity. The titanium dioxide nanoparticles are formed by reacting an inorganic titanium compound with water or ice to form an aqueous titanium compound. The aqueous titanium compound is reacted or combined with a dispersing agent. Titanium dioxide nanoparticles are precipitated to form a suspension. The formation of the titanium dioxide nanoparticles is influenced by the presence of bonding of the dispersing agent. The size of the nanoparticles can be advantageously controlled by selecting the ratio of titanium to dispersing agent. In addition, the titanium dioxide nanoparticles can be used in suspension form or filtered and dried to form a powder.

摘要： Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

摘要： Bimetallic catalyst precursors are manufactured from a plurality of molybdenum atoms and a plurality of atoms of a secondary transition metal (e.g., one or more of cobalt, iron, or nickel). The molybdenum atoms and the secondary transition metal atoms are each bonded with a plurality of organic anions (e.g., 2-ethyl hexanoate) to form a mixture of an oil-soluble molybdenum salt and an oil-soluble secondary transition metal salt. The molybdenum and/or the secondary transition metals are preferably reacted with the organic agent in the presence of a strong reducing agent such as hydrogen. To obtain this mixture of metal salts, an organic agent is reacted with the molybdenum at a temperature between about 100° C. and about 350° C. The secondary transition metal is reacted with the organic agent at a different temperature, preferably between 50° C. and 200° C. The metal salts are capable of forming a hydroprocessing metal sulfide catalyst in heavy oil feedstocks.

摘要： Supported catalysts are manufactured from a pretreated porous support material and a nanocatalyst solution of catalyst nanoparticles. The porous support material is pre-treated with a gaseous solvent (e.g., steam or alcohol) to protect the support material from cracking during impregnation of the nanocatalyst solution. The supported catalysts have more uniform size, lower attrition of metals during manufacturing and use, and improved distributions of metal loading compared to catalysts manufactured using known techniques. Hydrogen peroxide manufactured from such catalysts is less likely to be contaminated with catalyst metal.

摘要： Improved bi-metallic nanocatalysts are manufactured using a control agent to produce nanoparticles having a controlled crystal face exposure. The bi-metallic nanocatalyst particles are manufactured in a two-step process. In a first step, nanocatalyst particles are manufactured using the control agent and the primary metal atoms. The primary metal atoms and the control agent are reacted to form complexed metal atoms. The complexed metal atoms are then allowed or caused to form nanoparticles. The nanoparticles formed in the first step using the control agent have a desired crystal face exposure. In a second step, the secondary metal atoms are deposited on the surface of the primary metal nanoparticles. The secondary catalyst atoms maintain the same crystal face exposure as the primary metal nanoparticles.

摘要： Magnesium hydroxide nanoparticles are made from a magnesium compound that is reacted with an organic dispersing agent (e.g., a hydroxy acid) to form an intermediate magnesium compound. Magnesium hydroxide nanoparticles are formed from hydrolysis of the intermediate compound. The bonding between the organic dispersing agent and the magnesium during hydrolysis influences the size of the magnesium hydroxide nanoparticles formed therefrom. The magnesium hydroxide nanoparticles can be treated with an aliphatic compound (e.g., a monofunctional alcohol) to prevent aggregation of the nanoparticles during drying and/or to make the nanoparticles hydrophobic such that they can be evenly dispersed in a polymeric material. The magnesium hydroxide nanoparticles exhibit superior fire retarding properties in polymeric materials compared to known magnesium hydroxide particles.

摘要： Nanoparticle catalysts are manufactured by first preparing a solution of a solvent and a plurality of complexed catalyst atoms. Each of the complexed catalyst atoms has at least three organic ligands. The complexed catalyst atoms are reduced to form a plurality of nanoparticles. During formation of the nanoparticles, the organic ligands provide spacing between the catalyst atoms via steric hindrances and/or provide interactions with a support material. The spacing and interactions with the support material allow formation of small, stable, and uniform nanoparticles. The supported nanoparticle catalyst is then incorporated into a fuel cell electrode.
