    摘要: There is provided a process for preparing alloy nanoparticles having a desired size. The process comprises a combination of co-reduction of metal salts in the presence of a reducing agent, and multi-step seeded growth synthesis. Also provided is a material which comprises alloy nanoparticles made of at least two metals. A mean diameter of the particles of the material is between about 30 nm and 200 nm as measured by transmission electron microscopy (TEM), and the particles have a coefficient of variation smaller than about 15%.

    摘要: Processes for synthesizing metal nanoparticles, particularly copper nanoparticles, are described. The processes can involve reacting an insoluble complex of a metal salt with a reducing agent in a reaction mixture containing a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant. More specifically, processes for forming copper nanoparticles can involve forming a first solution containing a copper salt, a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant; allowing an insoluble complex of the copper salt to form from the first solution; combining a second solution containing a reducing agent with the insoluble complex; and forming copper nanoparticles from the insoluble complex. Such copper nanoparticles can be about 10 nm or smaller in size, more particularly about 3 nm to about 6 nm in size, and have a fusion temperature of about 200° C. or lower.
