As air pollution poses a great challenge around the globe, it is essential to fashion out a way
of efficiently degrading the air pollutants. Vacuum Ultraviolet (VUV)-based processes are an
emerging and promising technology for environmental remediation such as air cleaning,
wastewater treatment, and air/water disinfection. When VUV irradiation, photolysis,
photocatalysis, and ozone-assisted oxidation are involved at the same time, it results in the
fast degradation of air pollutants because of their strong oxidizing capacity. The mechanisms …
