Photocatalytic oxidation of volatile organic compounds (VOCS) in air using based materials
Heterogeneous photocatalytic oxidation is a promising technique for the removal of volatile organic pollutants (VOCs). It allows the oxidation of gaseous VOCs into carbon dioxide and water in the presence of semiconductor catalyt and UV light. Titanium dioxide (TiO2) represents one of the most effic...
