Catalysts for Fuel Cell Applications Using Electroless Deposition

摘要

In one embodiment, the present disclosure is directed to a process for electroless deposition of metal atoms on an electrode to form a core and shell structure. The process includes treating a carbon-containing support by contacting the carbon-containing support with a treatment. The carbon-containing support is impregnated with a core component metal to form at least one seed site on the carbon-containing support. A predetermined amount of shell component metal is deposited on the at least one seed site of the core component through electroless deposition by contacting the carbon-containing support with a metal salt and a reducing agent. The shell component forms at least one complete monolayer on the core component. The amount of the shell component deposited is predetermined by using the surface area of the core component.
