Abstract
Supported intermetallic compounds are produced by a two-step process. In the first step, a supported metal is formed, for example, by solvating a metallic salt such as nickel nitrate and applying it to a support medium. The treated support body is then heated in the presence of a reducing agent to produce elemental metal. The supported metal is then treated with a reactive organometallic or metal hydride compound to yield a supported intermetallic compound. For example, supported elemental nickel is treated with hexamethyldisilane to produce supported nickel silicide.
Claims11
A process for making a catalyst comprising the steps of:
- (a) forming a Group VIII-containing composition on a support and
- (b) contacting the Group VIII-containing support with a metal hydride or organometallic compound at a temperature sufficient to form an intermetallic compound wherein the metal hydride or organometallic compound contains at least one metal atom selected from the group consisting essentially of silicon, germanium, aluminum, boron, gallium, indium, and tin.
