Abstract
A composition having a gadolinium-, samarium-, or lanthanum-substituted porous cerium oxide and copper or gold nanoparticles. The composition can be exposed to electromagnetic radiation to form reactive oxygen species in the composition to decompose organophosphonate compounds. The composition may be made by forming a mixture of a cerium salt; a gadolinium, samarium, or lanthanum salt; and an epoxide; forming gel from the mixture; and drying the gel to form an aerogel, a xerogel, or an ambigel. Copper or gold nanoparticles are added or formed at any point in the method.
Claims8
