    摘要: A metallic alloy includes Cu and one or more metals M selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni and Zn, wherein the alloy has a surface in the form of a vermiculated arrangement of irregular, nanoporous lands separated by troughs or channels. It can be made by contacting a precursor alloy including Cu, M and Al with a caustic liquid under conditions sufficient to remove the Al. Or, a metallic alloy includes Cu and one or more metals M selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni and Zn, wherein the one or more metals M in total constitute in a range of 3 at. % to 7 at. %, relative to the total of Cu and M. Both types of alloy can be used as an electrocatalyst in a water electrolyzer or a hydrogen fuel cell.

    摘要: A method for preparing ethylene glycol from cellulose uses the cellulose as the feed for the reaction. The cellulose conversion is performed over catalysts which are composed of the metallic state, carbides, nitrides, or phosiphides of molybdenum or tungsten, and metallic cobalt, nickel, ruthenium, rhodium, palladium, iridium, and platinum of the group 8, 9, or 10 transition metals. The catalytic conversion of cellulose is conducted at 120 to 300° C. and hydrogen pressure 1 to 12 MPa under the hydrothermal conditions to achieve the high efficiency, high selectivity, and high yield of ethylene glycol. Compared to the existing method of preparing ethylene glycol from ethylene, the method, using the renewable raw material for the reaction, is friendly to the environment, and has high atom economy.

    摘要: Tungsten carbide catalysts are used in preparation of ethylene glycol by hydrogenating degradation of cellulose. The catalyst includes tungsten carbide as main catalytic active component, added with small amount of one or more transition metals such as nickel, cobalt, iron, ruthenium, rhodium, palladium, osmium, iridium, platinum, and copper as the second metal, supported on one or more porous complex supports such as active carbon, alumina, silica, titanium dioxide, silicon carbide, zirconium oxide, for conversion of cellulose to ethylene glycol. The catalyst realizes high efficiency, high selectivity, and high yield in the conversion of cellulose to ethylene glycol at the temperature of 120-300° C., hydrogen pressure of 1-10 MPa, and hydrothermal conditions. Compared to the existing industrial synthetic method of ethylene glycol using ethylene as feedstock, the invention has the advantages of using renewable raw material resources, environment friendly process, and excellent atom economy.
