Abstract

Emissions of nitrogen oxide (NOx) should be diminished to address the facts of urban air pollution and its health and environmental consequences. This study explores the potential of NOx reduction of photovoltaic pollutants in cement mortar using titanium dioxide (TiO2) as a photovoltaic material. NOx is one of the major pollutants of urban air, related to the problems of smog and acid rain, with serious health hazards. The study focuses on the development of sustainable construction materials using the photocatalytic property of TiO2 to reduce NOx emissions. Mortar samples were created with different concentrations of TiO2 (1.5%, 2%, and 2.5%) and tested for NOx reduction and compressive strength over 7 and 28 days. The results indicate significant NOx reduction, with the highest value coming from the mix of 2.5% TiO2 at 2433 ppm. In addition, the study checked the mechanical properties of such mortars and thereby declared that the optimum compressive strength is found with a mix of 1.5% TiO2. The results reflect the dual achievement of the mortars containing TiO2 – mitigation of air pollution and structural requirements. Such research indicates the massive potential of photocatalytic mortars in the domain of urban environments that were cleaner and greener, and simultaneously brought development into sustainable construction activities.
