摘要：
An active material is disclosed which comprises a metal oxide/hydroxide surface having chemically bonded to reactive sites thereon a substantially monomolecular layer of organic acid molecules. Each organic acid molecule is chemically bonded to a reactive site on the oxide/hydroxide surface through a phosphorus-containing acid group selected from the group consisting of a phosphonic acid group and a phosphinic acid group. Each organic acid molecule also comprises an unreacted acid group oriented away from the metal oxide/hydroxide surface and selected from the class consisting of a phosphonic acid group, a phosphinic acid group, a sulfonic acid group, and a carboxylic acid group.
