摘要:A method of making a titanium dioxide nanowire array includes contacting a substrate with a solvent comprising a titanium (III) precursor, an acid, and an oxidant while microwave heating the solvent, thereby forming a hydrogen titanate H2Ti2O5.H2O nanowire array. The hydrogen titanate nanowire array is annealed to form a titanium dioxide nanowire array. The substrate is seeded with titanium dioxide before starting the hydrothermal synthesis of the hydrogen titanate nanowire array. The titanium dioxide nanowire array is loaded with a platinum group metal to form an exhaust gas catalyst. The titanium dioxide nanowire array can be used to catalyze oxidation of combustion exhaust.

标 题:Synthesis of platinum-alloy nanoparticles and supported catalysts including the same
发明人：CARPENTER MICHAEL K
权利人:GM GLOBAL TECH OPERATIONS INC
摘要:Methods of synthesizing platinum-nickel-alloy nanoparticles and supported catalysts comprising the nanoparticles are provided. The methods may comprise forming a reaction mixture in a reaction vessel; heating the reaction mixture sealed in the reaction vessel to a reaction temperature; maintaining the temperature of the reaction vessel for a period of time; cooling the reaction vessel; and removing platinum-alloy nanoparticles from the reaction vessel. The reaction mixture may comprise a platinum precursor, a nickel precursor, a formamide reducing solvent, and optionally a cobalt precursor. In some embodiments the reaction temperature is at or below the boiling point of the formamide reducing solvent, such as from about 120° C. to about 150° C., for example. The platinum-alloy nanoparticles provide favorable electrocatalytic activity when supported on a catalyst support material.

摘要:A catalyst structure for synthesis gas production of a synthesis gas that contains carbon monoxide and hydrogen, the catalyst structure being provided with a carrier that has a porous structure, while being configured from a zeolite type compound; first catalyst particles that contain one or more iron group elements which are selected from the group consisting of nickel (Ni), iron (Fe) and cobalt (Co); and second catalyst particles that contain one or more platinum group elements which are selected from the group consisting of platinum (Pt), palladium (Pd), rhodium (Rh) and ruthenium (Ru). The catalyst structure for synthesis gas production has passages in communication with each other within the carrier. The first catalyst particles are present at least in the passages of the carrier; and the second catalyst particles are present at least either inside the carrier or on the outer surface of the carrier.
