Description
Air quality is one of the key factors that determine human health and longevity. The air that we breathe can be contaminated with various impurities such as; sulfur oxides (SOX), carbon monoxide (CO), ozone (O3) and the volatile organic compounds (VOCs).1 The primary idea of this work was to achieve the synergistic action between immobilized photocatalyst titanium dioxide, TiO2, on the surface of recycled rubber tiles and solar radiation. The synergistic action triggers redox reactions on the photocatalysts surface to degrade various impurities previously mentioned.1 TiO2 irradiated with UV light, can decompose many organic compounds to water, carbon dioxide, and mineral acids or their salts.2
Immobilization was validated by SEM-EDS and FTIR analysis. The stability and environmental impact were investigated by leaching test, AAS and TOC analyses. Photocatalytic tests were done in a custom-made wind tunnel reactor with a simulated polluted atmosphere to confirm the activity. Successful immobilization of TiO2 on the reference rubber tile was achieved, and the photocatalytic activity of the immobilized layer was confirmed by successful degradation of ammonia.
