Adsorption and degradation of model volatile organic compounds by a combined titania-montmorillonite-silica photocatalyst

► Adsorptive combined titania-montmorillonite-silica photocatalysts synthesized. ► All catalysts had relatively high adsorption capacities of multinary VOCs. ► All catalysts preferred to adsorb the VOCs with higher polarity. ► CTMS80 can effectively photocatalytically remove VOCs of various components.
