Disclosed is a method of irradiating a composition having water and hydrogen-terminated nanodiamonds with light that generates water-solvated electrons from the nanodiamonds. The method can be used to degrade fluoroalkyl compounds such as perfluorooctane sulfonate.

Nanodiamond reduction photochemistry

An oxide-based aerogel having cerium and nickel may be used as a water-gas shift reaction catalyst without producing methane as a byproduct. It may be made by forming a gel from a cerium salt and a nickel salt solution and converting the gel to an aerogel.

NiCeOx aerogels for methane suppression in the water-gas shift reaction

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.

Stabilization of reactive oxygen species in ceria-based composite aerogels

A composition having: titania aerogel having titania nanoparticles and copper nanoparticles. Each of the copper nanoparticles is in contact with more than one of the titania nanoparticles. A method of: providing a titania aerogel, and forming or depositing copper nanoparticles onto the surface of the titania aerogel.
