Photocatalytic Degradation of Organic Pollutants and Airborne Pathogen in Air

  • Chapter
  • First Online:
Photocatalysis for Environmental Remediation and Energy Production

Part of the book series: Green Chemistry and Sustainable Technology ((GCST))

Abstract

According to World Health Organization, air pollution kills millions of people worldwide every year. In addition, several epidemiological findings have uncovered the impacts of air pollution on respiratory and cardiovascular systems. This chapter presents current knowledge of human health concerns caused by volatile organic compounds (VOCs) and biological contaminants. These contaminants contribute to air pollutants that impair all environmental elements. Heterogeneous photocatalytic processes using semiconductor photocatalyst would serve as a promising technology and an efficient approach for removing VOCs and airborne pathogens. Considering the potentially toxic effect of these air pollutants, emerging mitigation approaches such as the photocatalysis process are explained elaborately in this chapter, including fundamental principles of photocatalysis, reaction mechanism, reaction kinetics, and photoreactor designs suitable for air purification. Furthermore, the photocatalytic process as a paradigm explores existing techniques utilized in research and commercial applications. Significant efforts have been made to include information from worldwide sources for this investigation.
