Improving Nitrogen Oxides and Ammonia Gas Sensing Capabilities of TiO2

Over the last decades an interest has arisen in eliminating the increased emissions and serious detrimental effects of atmospheric pollutants such as nitrogen oxides and ammonia molecule. A convenient solution would be a process that could effectively use some metal oxide nanoparticles for adsorbing harmful gas molecules during the surface processes. The molecular adsorption of NOx and NH3 molecules on the photocatalyst titanium dioxide (TiO2) is such a process.
