Heterogeneous Photocatalysts Based on TiO2 for Abatement of Hazardous Air Pollutants

A mixture of suspended solid particles and gases coming from car emissions, chemicals from factories, dust, and pollen in the air is called air pollution. Human exposure to common hazardous air pollutants such as NOx, SOx, CO, H 2 S, NH 3 , and VOCs is associated with chronic respiratory diseases and cancer. Moreover, exposure to one of the most dangerous forms of air pollution very fine particulates PM 2.5 can cause such deadly illnesses as lung cancer, stroke, and heart disease. Given all these facts, this paper discusses newly developed advanced smart building materials based on TiO 2 with self-cleaning and pollutant removal capability from the environment.
