    摘要： Deactivation resistant photocatalysts can be formulated by coating one or more photocatalyst crystals onto a suitable substrate. The photocatalyst crystals are doped with a dopant M. The dopant could be used to repel the silicon-based compound or be used to attract the silicon-based compound. In one embodiment, the dopant can uniformly be distributed in the photocatalyst crystals. In another embodiment, the dopant can be introduced only to photocatalyst crystals between about 0.1 to about 2 nanomenters below the surface of the structure. In another embodiment, the doped photocatalyst crystals can be interdispersed with non-doped photocatalyst crystals.

    摘要： A durable Pd-based alloy is used for a H2-selective membrane in a hydrogen generator, as in the fuel processor of a fuel cell plant. The Pd-based alloy includes Cu as a binary element, and further includes “X”, where “X” comprises at least one metal from group “M” that is BCC and acts to stabilize the β BCC phase for stability during operating temperatures. The metal from group “M” is selected from the group consisting of Fe, Cr, Nb, Ta, V, Mo, and W, with Nb and Ta being most preferred. “X” may further comprise at least one metal from a group “N” that is non-BCC, preferably FCC, that enhances other properties of the membrane, such as ductility. The metal from group “N” is selected from the group consisting of Ag, Au, Re, Ru, Rh, Y, Ce, Ni, Ir, Pt, Co, La and In. The at. % of Pd in the binary Pd—Cu alloy ranges from about 35 at. % to about 55 at. %, and the at. % of “X” in the higher order alloy, based on said binary alloy, is in the range of about 1 at. % to about 15 at. %. The metals are selected according to a novel process.

    摘要： A cermet inert anode having a reduced level of contaminating surface metal is disclosed. Methods for preparing cermet inert anodes and methods for treating cermet inert anodes are also disclosed. The methods generally use an oxidizing agent to convert metals on the surface of the anode to inert oxides and/or to otherwise remove the metal contaminants. The inert anodes of the present invention may be used in electrolytic reduction cells for the production of commercial purity aluminum, as well as other metals.

    摘要： A method of controlling bulk absorption of atomic hydrogen and facilitating degassing of hydrogen from aluminum alloy workpieces during heat treatments in furnaces with ambient and/or moisture-laden atmospheres by exposing the surface of the workpieces to a low molecular weight solution or dispersion of an alkyl phosphonic acid, an olefinic phosphonic acid or an aryl phosphonic acid before subjecting the workpieces to heat treatments. The workpieces exposed to the phosphonic acid solution or dispersion are subjected to heat treatment in furnaces having ambient or moisture-laden atmospheres. The solution or dispersion involves chemical species that are deposited onto the aluminum surface from the phosphonic acid solution or dispersion which substantially decrease the amount of atomic hydrogen entering the bulk of the workpieces from their surfaces during heat treatment and, in addition, facilitate removal of atomic and molecular hydrogen from the bulk of the workpieces during heat treatment.
