Abstract:
A method of producing catalyst powder of the present invention has a step of precipitating a carrier in a reversed micelle, and a step of precipitating at least one of a noble metal particle and a transition metal particle in the reversed micelle in which the carrier is precipitated. By this method, it is possible to obtain catalyst powder excellent in heat resistance and high in the catalytic activity.
