    • 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.
    • 本教导涉及单金属和合金纳米颗粒以及用于制备单一金属和合金纳米颗粒的合成方法。 本教导包括制备金属纳米颗粒的方法,该方法包括使含金属的组分与还原剂(任选地与封端剂)在溶剂体系中接触以形成反应混合物。 反应混合物可以加热回流,冷却,并且可以从反应混合物中沉淀所需的金属纳米颗粒。 任选地,金属纳米颗粒可以被支撑在合适的支撑材料,例如高表面积的支撑材料上。 载体材料可以与还原剂一起并入反应混合物中。 本教导包括制备合金纳米颗粒的方法,该方法包括在溶剂系统中使至少两种含金属的组分与还原剂和至少一种封端剂接触以形成反应混合物,加热和回流反应混合物,冷却 反应混合物,并从冷却的反应混合物中沉淀合金纳米颗粒。
