Abstract
A supported composite particle material comprises: a composite particle formed of an oxidized nickel and X (wherein X represents at least one of elements selected from the group consisting of nickel, palladium, platinum, ruthenium, gold, silver and copper); and a support on which the composite particle is supported, the supported composite particle material having a supported layer in which the composite particle is localized.
Claims16
A supported composite particle material comprising:
- a composite particle formed of an oxidized nickel and X (wherein X represents at least one of elements selected from the group consisting of nickel, palladium, platinum, ruthenium, gold, silver and copper);
- and
- a support on which the composite particle is supported,
- wherein the supported composite particle material comprises a supported layer in which the composite particle is localized.
A process for producing a supported composite particle material in which the composite particle formed of an oxidized nickel and X (wherein X represents at least one of elements selected from the group consisting of nickel, palladium, platinum, ruthenium, gold, silver and copper) is supported onto a support, comprising:
- a first step of obtaining a mixture at a temperature of at least 60° C. by mixing an aqueous slurry containing a support on which is supported an oxide of at least one of basic metals selected from the group consisting of alkaline metals, alkaline earth metals and rare earth metals, and an acidic aqueous solution of a soluble metal salt containing nickel and the X;
- and
- a second step of heat-treating a precursor contained in the mixture.
