Abstract: An active material is disclosed comprising a metal oxide/hydroxide surface having chemically bonded to reactive sites thereon, a monolayer of a phosphorus-containing organic material comprised of a phosphorus-containing group and a carbon-containing group. The bond to the metal oxide/hydroxide surface is formed by reaction of the phosphorus-containing group with the metal oxide/hydroxide surface, so that the carbon-containing group of the material is oriented away from the metal oxide/hydroxide surface.
