Abstract
In a method of producing a particulate electrocatalyst composition, a precursor medium comprising at least a first metal precursor, a liquid vehicle, and a substrate precursor to substrate particles is atomized into precursor droplets. The droplets are then heated to a reaction temperature of not greater than 700° C. to form composite particles comprising said first metal at least partly in an oxide form dispersed on said substrate particles. The composite particles are then collected and are heated at a first treatment temperature no greater than 250° C. in the presence of a reducing atmosphere to at least partly convert said oxide form to the metal.
