Novel integrated approach of adsorption and photo-oxidation using Ag-TiO₂/PU for bioaerosol removal under visible light.

ABSTRACT: We investigated a novel approach by synthesizing an integrated material, which could act as both adsorbent and photocatalytic material, for bioaerosol purification under visible light conditions. Ag was used as a dopant agent to enhance photocatalytic activity of TiO₂, leading to high photocatalytic activity of the doped TiO₂ even under visible light. Under visible light, the doped TiO₂ photocatalyst could produce oxy radicals, oxidative agents, that participate in oxidation reactions to decompose important organic components of bacteria, leading to death or removal of bacteria from an aerosol. Adsorption property was integrated into the enhanced TiO₂ photocatalyst by using polyurethane (PU), a honeycomb structure material, as a substrate for coa
