Abstract

Photocatalytic materials are considered an effective solution to improve air quality in urban areas and have been extensively studied in the past decade. The use of nanoparticles as photocatalyzers proved very effective however, the operational conditions can determine how successful the solution will be. For mortars containing nanoparticle of titanium dioxide, the photocatalytic degradation of air pollutants can be compromised by surface contamination, the pollutant's concentration, and the deactivation time. In this work, the influence of these operational parameters has been studied alongside with a method to improve the photocatalytic activity by using Fe3+ ion doping.
