Evaluation of Titanium Dioxide to Reduce Air Pollutants
Year: 2024
Type: article
Abstract: This report presents an evaluation of titanium dioxide (TiO2) for reducing air pollutants. The introduction provides background information on NMIT, the Department of Civil Engineering, and the testing lab, Bangalore Test House. The literature review explores the potential environmental applications of TiO2 nanoparticles, the morphological control of anodic crystalline TiO2 nanochannel films, and the use of metal oxide titanium oxide (M-TiO2) for visible light induced CO2 photoreduction. The aim and scope of the present investigation are outlined, focusing on the effectiveness of applying TiO2 to surface materials to produce a greener urban environment. The main objective is to study the effect of TiO2 photo catalysis on more exposed surfaces to daily environmental pollutants such as concrete pavements, road dividers, walls exposed to high pollution areas, and vehicles. The experimental investigation includes SEM and XRD tests, leakage tests, and NO2 reduction tests for samples with and without TiO2 coating. The results show that TiO2 coated surfaces are effective at reducing NO2 concentrations in the presence of UV light. The conclusion is that TiO2 coating can be a promising approach to degrading harmful air pollutants and improving air quality.
