Abstract
A method of treating the surface of a substrate by thermally spraying large size particles, >10 micrometers, of a composition such as a metal hydroxide, carbonate, or nitrate directly onto the substrate whereby a small size particle coating, <5 microns and more particularly <3, is formed on the substrate, enhancing the surface area and porosity properties of the substrate, and substrates with metal oxide surfaces produced thereby.
