Abstract
This study aims to reduce the concentration of nitrogen in the indoor and outdoor atmosphere and its harmful compounds. Nitrogen dioxide is a gas emitted mainly by automobiles, trucks, power plants, and some industrial plants, with the highest concentrations of nitrogen dioxide in terms stops the good distribution of atmospheric pollution which led to higher COVID-19 cases in recent trends. By establishing chemical coatings on the building materials will have a significant effect. The exterior modification on the glass is done by mixing silica gel along with titanium dioxide to adsorb the accumulated NO2 present in the buildings. Here, spray coating and dip coating technologies were used to coat the solution on the normal glass. The coating was found to be hydrophobic and showed better performance in the fastness test results. The size of the film is 45 to 55 nm. The percentage of adsorption confined to 20%. The least number of days of the period of replacement was found to be 24 days in this research for the most vulnerable conditions having air pollution levels greater than 500μgm3. Finally, our study proves that establishing coatings can significantly reduce air pollution by reducing the percentage of NO2 by 20% in a particular environment.
