    摘要: The present teachings are directed to preparation of carbon-supported CoSe2 nanoparticles via an in situ surfactant free method, and use of the same for oxygen reduction and hydrogen evolution reactions. The CoSe2 nanoparticles have two kinds of structure after heat treatment at different temperatures: orthorhombic at 300° C. and cubic at 400° C. The latter structure has higher oxygen reduction activity and hydrogen evolution activity than the former in 0.5 M H2SO4. Electron transfers of about 3.5- and about 3.7-electrons were observed for 20 wt. % CoSe2/C nanoparticles, after heat treatment at 300° C. and 400° C., per oxygen molecule during the oxygen reduction process, respectively.

    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.
