Abstract:
1. A method of coating a porous particle layer of metal-metal oxide on a metal substrate, comprising the steps of: (1) washing the metal substrate with an acid or alkali, followed by drying the washed metal substrate; (2) coating metal particles onto the metal substrate to form a metal particle layer; (3) partially sintering the metal particle layer at 600–1500° C. under vacuum or under an inert atmosphere; and (4) calcining the metal substrate with the partially sintered metal particle layer coated thereon at 400–1200° C., to form a metal oxide film on a surface of the metal particles, thereby preparing the porous particle layer of metal-metal oxide coated on the metal substrate.
