专利号:US-10913056-B2 优先权日:2017-07-31 标 题:Method for synthesis of copper/copper oxide nanocrystals 发明人:CHEN GUGANG; HARUTYUNYAN AVETIK; RAO YI; LI XIA 权利人:HONDA MOTOR CO LTD; UNIV TEMPLE; TEMPLE UNIV OF THE COMMONWEALTH SYSTEM OF HI 摘要:A simple approach to produce mixed Cu/Cu 2 O nanocrystals having a specific morphology by controlling the reaction temperature during Cu/Cu 2 O nanocrystals synthesis. Other variables are kept constant, such as the amount of reactants, while the reaction temperatures is maintained at a predetermined temperature of 70° C., 30° C. or 0° C., which are used to produce different and controlled morphologies for the Cu/Cu 2 O nanocrystals. The reaction mixture includes a copper ion contributor, a capping agent, a pH adjustor, and reducing agent. The reaction mixture is held at the predetermined temperature for three hours to produce the Cu/Cu 2 O nanocrystals. The synthesis method has advantages such as mass production, easy operation, and high reproducibility.
专利号:US-8110021-B2 优先权日:2008-07-28 标题:Synthesis of PtCo nanoparticles 发明人:ZHONG CHUAN-JIAN; LUO JIN; XU ZHICHAUN; HE TING 权利人:ZHONG CHUAN-JIAN; LUO JIN; XU ZHICHAUN; HE TING; HONDA MOTOR CO LTD; UNIV NEW YORK STATE RES FOUND 摘要:Synthesis of nanoparticles with particle size control is provided by the method of using two different metal-containing precursors, a capping component, an optional reducing agent, and then contacting the two precursors with the capping component to form a reaction solution, which is heated to produce first and second metals-containing nanoparticles. By controlling the ratio of the concentration of the capping component to the total concentration of the two metal-containing precursors, the nanoparticles can have diameters ranging between about 1 nm to about 15 nm. A decrease in the concentration of the capping component typically increases the size of the nanoparticles. Preferred compositions include Pt and Co-containing alloy nanoparticles. Controlled synthesis of larger, about 6 nm to about 12 nm, sized nanoparticles can be achieved in a solvent-free reaction process.

The process comprises the step of simultaneously reducing a copper II salt and a gold halide by 1,2-hexadecanediol in diphenyl ether, and 1-dodecanethiol as well as surfactants 1-adamantanecarboxylic acid and 1-hexadecylamine. The copper II salt may be copper (II) acetylacetonate, copper chloride, copper sulfate, or copper phosphate. The gold halide may be chloroauric acid, gold chloride, gold bromide, or tetrabromoauric acid. The reduction may occur at a temperature between about 160 and 180 degrees Celsius. The copper II salt may be copper (II) acetylacetonate and the gold halide may be chloroauric acid.
