    摘要: The present invention provides a method of making a noble metal catalyst, where the noble metal is distributed on the surface of special composite carrier particles. Nanometer sized oxide particles are first dry coated by an impact mixing process on the surface of larger alumina particles. In general, this dry coating process coats the nanometer sized particles on the surface of the alumina particles. A suitable solution of noble metal(s) compound is then soaked on the surface of the composite carrier particles. Ultimately, the noble metal compound is decomposed by calcining and noble metal particles dispersed with large effective surface area on the composite carrier particles. The resultant catalyst structure improves catalyst performance while making efficient and effective use of the expensive noble metal.

    摘要: One embodiment of the invention includes a photovoltaic system that provides both electricity and low-grade heat, together with many options of utilizing the energy. The electricity may efficiently be used to drive a high-pressure electrolyzer that produces hydrogen. The hydrogen pressure may be boosted to a final compression of at least 700 bar. In one embodiment the pressure may be boosted using a metal-hydride compressor and stored. The stored high pressure hydrogen may be used to fill fuel-cell electric vehicle (FCEV) tanks. The electricity can also be used to efficiently charge the batteries in an extended range electric vehicle (EREV).

    摘要: Rare earth element(s) doped alumina nanowires are formed by a thermal evaporation method in which vapor from aluminum powder and vapor from a rare earth element compound (such as an halide) are reacted in an oxygen-containing inert gas stream to form alumina which deposits as alumina nanowires and as a rare earth element and oxygen-containing material that deposits with and/or on the alumina nanowires. Where the RE-doped alumina nanowires are to be used as catalyst supports, a catalyst material, such as platinum, may be deposited as small particles on the nanowires.

    摘要: Carbon with mesopores (about two to fifteen nanometers in average pore size) is made using sucrose as a source of carbon, and silica and phosphoric acid as templates for the mesopore structure in the carbon. A silica sol is prepared in a water/ethanol medium and sucrose is dispersed in the sol. Phosphoric acid may be added to the sol to control pore size in the mesopore size range. The sol is dried, carbonized, and the silica and phosphate materials removed by leaching. The residue is a mesoporous carbon mass having utility as a catalyst support, gas absorbent, and the like.
