摘要： The present teachings are directed toward single metal and alloy nanoparticles and synthesis methods for preparing single metal and alloy nanoparticles. The present teachings include a method of preparing metal nanoparticles which method includes contacting a metal- containing component with a reducing agent, optionally with a capping agent, in a solvent system to form a reaction mixture. The reaction mixture can be heated to reflux, cooled, and the desired metal nanoparticles can be precipitated from the reaction mixture. Optionally, the metal nanoparticles can be supported on a suitable support material, such as, a high surface area support material. The support material can be incorporated into the reaction mixture, for instance, along with the reducing agent. The present teachings include a method of preparing alloy nanoparticles which method includes contacting at least two metal-containing components with a reducing agent and at least one capping agent in a solvent system to form a reaction mixture, heating and refluxing the reaction mixture, cooling the reaction mixture, and precipitating the alloy nanoparticles from the cooled reaction mixture.

摘要： A supported catalyst is prepared by a process that includes establishing shell-removal conditions for a supported catalyst intermediate that includes capped nanoparticles of a catalyst material dispersed on a carbon support. The capped nanoparticles each include a platinum alloy core capped in an organic shell. The shell-removal conditions include an elevated temperature and an inert gas atmosphere that is substantially free of oxygen. The organic shell is removed from the platinum alloy core under the shell-removal conditions to limit thermal decomposition of the carbon support and thereby limit agglomeration of the catalyst material such that the supported catalyst includes an electrochemical surface area of at least 30 m 2 /g Pt .

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.
