Abstract
A photocatalytic device for reacting with volatile organic compounds includes a photocatalyst and at least one additive, such as hafnium oxide and zirconium oxide, that is capable of forming a stable silicate with silicon dioxide. The additive reacts with volatile silicon-containing compounds to form stable silicate compounds. As a result, the silicon-containing compounds are unavailable for deactivation of the photocatalyst.
