    Abstract: A method for forming a supported metal-containing powder. The method comprises forming a dispersion of a particulate support in a solution, which comprises a solvent and a dissolved metal. Heat is removed from the dispersion to precipitate the dissolved metal from the solution onto the particulate support. Preferably, enough heat is removed to freeze the solution. The heat is preferably removed from the dispersion by contacting a container containing the dispersion with a cryogenic liquid, such as liquid nitrogen. After precipitating the dissolved metal onto the particulate support, the particulate support is separated from the solution, preferably by freeze-drying, to yield the supported metal-containing powder, which comprises the particulate support and a precipitated metal thereon.

    Abstract translation: 一种形成负载的含金属粉末的方法。 该方法包括在包含溶剂和溶解金属的溶液中形成颗粒载体的分散体。 从分散体中除去热量,使溶解的金属从溶液中沉淀到颗粒载体上。 优选地,除去足够的热量以冷冻溶液。 通过使含有分散体的容器与液氮如低温液体接触,优选从分散体除去热量。 在将溶解的金属沉淀到颗粒载体上之后,将颗粒载体从溶液中分离出来,优选通过冷冻干燥,得到包含颗粒载体和载于其上的沉淀金属的负载的含金属粉末。
