  • Patent number: 10875015
    Abstract: Methods for making porous materials having metal alloy nanoparticles formed therein are described herein. By preparing a porous material and delivering the precursor solutions under vacuum, the metal precursors can be uniformly embedded within the pores of the porous material. Once absorption is complete, the porous material can be heated in the presence of one or more functional gases to reduce the metal precursors to metal alloy nanoparticles, and embed the metal alloy nanoparticles inside of the pores. As such, the metal alloy nanoparticles can be formed within the pores, while avoiding surface wetting and absorption problems which can occur with small pores.

  • Patent number: 10662509
    Abstract: A method for making covetic metal-carbon composites or compositions by electron beam melt heating under vacuum (pressure <10?3 Torr) is described herein. This fabrication method is advantageous, in that it provides oxygen-free covetic materials in a process that allows precise control of the composition of the covetic material to be produced. The method described herein also can be applied to produce multi-element-carbon composites within a metal or alloy matrix, including high melting temperature materials such as ceramic particles or prefabricated nano- or micro-structures, such as carbon nanotubes or graphene compounds. The covetic reaction between metal and carbon takes place under the influence of flowing electrons through the melted metal-carbon precursor. This process creates strong bonding between nanocarbon structure and the metal elements in the melt.

  • Publication number: 20140031195
    Abstract: The method for producing a material loaded with gold nanoparticles, includes: impregnating a carrier with an anionic gold-hydroxo complex solution including a transparent solution that has a pH of not lower than 8, does not contain a halide anion, and contains a conjugate base of a weak acid not coordinated to gold and an anionic hydroxo complex of trivalent gold having a square planar molecular geometry whose at least one ligand is OH? and not containing a halide anion as a ligand; removing water; heating; and washing with water. According to the method, in a method for preparing a gold nanoparticle catalyst using a liquid phase method, a gold compound not containing a halide such as chloride is used as a raw material, and the gold compound can be supported efficiently. Furthermore, a gold nanoparticle-loaded catalyst having high activity can be obtained through a simple preparation method.

  • Patent number: 8603934
    Abstract: A carbon nanosphere has at least one opening. The carbon nanosphere is obtained by preparing a carbon nanosphere and treating it with an acid to form the opening. The carbon nanosphere with at least one opening has higher utilization of a surface area and electrical conductivity and lower mass transfer resistance than a conventional carbon nanotube, thus allowing for higher current density and cell voltage with a smaller amount of metal catalyst per unit area of a fuel cell electrode.

  • Patent number: 8568678
    Abstract: The reductive removal of nitrogen oxides from the exhaust gas from internal combustion engines operated predominantly under lean conditionstakes place in a selective catalytic reduction (SCR) of the nitrogen oxides by means of ammonia or a compound which can be decomposed into ammonia as reducing agent. Conventional SCR catalysts typically have a relatively narrow working temperature window, usually 350° C. to 520° C., in which good nitrogen oxide conversions can be achieved with sufficient selectivity. SCR catalyst formulations whose working window is in the temperature range from 150° C. to 350° C. generally not be used at higher temperatures since they oxidize the ammonia required as reducing 18 agent to nitrogen oxides at above 350° C. To cover the entire exhaust gas temperature range typical of vehicles having been operating internal combustion enginesextending from 200° C. to 600° C.
