The invention relates to a polyoxometalate topical composition for removing a contaminant from an environment, comprising a topical carrier and at least o ne polyoxometalate, with the proviso that the polyoxometalate is not H5PV2Mo10O40; K5Si(H2O)MnIIIW11O39; K4Si(H2O)MnIVW11O39; or K5CoIIIW12O40. T he invention further relates to a method for removing a contaminant from an environment by the composition and contacting a polyoxometalate powder or a polyoxometalate coating with the environment. It further relates to a modifi ed polyoxometalate, comprising the admixture of (1) a polyoxometalate and (2) a cerium, a silver, a gold, a platinum compound, or a combination thereof. The invention further relates to a method for removing a contaminant from an environment by contacting a modified material comprising (1) a material and (2) a metal compound comprising a transition metal compound, an actinide compound, a lanthanide compound, or a combination thereof, wherein the metal compound is not a polyoxometalate. The modified material comprises (1) a material comprising a topical carrier, a powder, a coating, or a fabric, and (2) a metal compound comprising a transition metal compound, an actinide compound, a lanthanide compound, or a combination thereof, wherein the metal compound is not a polyoxometalate. The invention further relates to an artic le comprising the modified material.
