Abstract The photocatalytic oxidation of seven typical indoor volatile organic compounds (VOCs) is experimentally investigated using novel nanocrystalline TiO2 dip-coated catalysts. Not only the role of hydrophilicity of the reactants but also other physico-chemical properties and molecular descriptors are studied and related to kinetic and equilibrium constants. The main objective of this work consists in establishing simple relationships that will be useful to deepen the understanding of gas-phase heterogeneous photocatalytic mechanisms and for the prediction of degradation rates of these VOCs using an indoor air treatment process.

Catalytic Deactivation

AbstractGas-phase photocatalytic oxidation of different classes of volatile organic compounds (VOCs), including alkanes, ketones, alcohols, chlorinated compounds and aromatic compounds, was investigated using an annular thin film reactor. For all organic compounds tested, catalytic deactivation was not observed, except for toluene (506 ppmv). For this compound, maximum destruction (87%) was maintained during the first 60 min of irradiation, dropping steadily due to catalyst deactivation to 20% after 150 min. The use of ozone as auxiliary agent in the photocatalytic oxidation of toluene and pyridine was also tested. For toluene, when O
