摘要: Metallic aerogel compositions comprising an aerogel, e.g., RF or carbon aerogel, having metallic particles dispersed on its surface are disclosed. The aerogel compositions can have a uniform distribution of small metallic particles, e.g., 1 nanometer average particle diameter. Also disclosed are processes for making the aerogel compositions comprising contacting an aerogel with a supercritical fluid containing a metallic compound. The aerogel compositions are useful, for example in the manufacture of fuel cell electrodes.

摘要: A process for making an aerogel-electrolyte-metal composite includes contacting an aerogel with an electrolyte to form an aerogel-electrolyte composite; contacting the aerogel-electrolyte composite with a metal precursor to form an aerogel-electrolyte-precursor composite; and converting the metal precursor of the aerogel-electrolyte-precursor composite to metal crystals to form the aerogel-electrolyte-metal composite. In addition, an aerogel-electrolyte-metal composite is formed by the process, wherein the average longest dimension of the metal crystals is about 1 to about 3 nanometers, and wherein the metal crystals are about 30% to about 100% dispersed.
