Abstract
A technique may produce a composite at a low temperature by a reducing agent that is easy to handle. A technique may produce a composite in which a metal simple substance or a metal oxide derived from reduced cations, or both of them are supported on a carrier. The technique may include at least: preparing a liquid phase mixture containing at least an alcohol compound as a first reducing agent, a phosphinic acid or a salt thereof as a second reducing agent, the carrier, and a source compound of one or more cations selected including Au, Ag, Cu, Pt, Rh, Ru, Re, Pd, and/or Ir; and reducing the cations in the liquid phase mixture.
Claims16
A method for producing a composite in which a metal and/or a metal oxide are supported on a carrier, the method comprising:
- preparing a liquid phase mixture comprising an alcohol compound as a first reducing agent, a phosphinic acid or a salt thereof as a second reducing agent, the carrier, and at least one metal compound of one or more cations selected from the group consisting of Au, Ag, Cu, Pt, Rh, Ru, Re, Pd, and Ir;
- and
- reducing the cations in the liquid phase mixture;
- wherein:
- a content of the phosphinic acid or the salt thereof is stoichiometrically 1 time or more and 20 times or less with respect to an amount of the metal and/or metal oxide to be supported on the carrier.
