A critical innovation of photocatalytic degradation for toxic chemicals and pathogens in air

초록

Air pollution by toxic chemicals and pathogens (bacteria, viruses, and fungi) has become one of the most critical problems worldwide because it has strong negative impacts on human health, both indoors and outdoors. Photocatalysis is a promising candidate to purify the atmosphere by removing pollutants among several physicochemical and biological methodologies. In this review, we discuss photocatalytic materials used for air purification, advanced methodologies for photocatalysts synthesis, and principles of photocatalytic nanoparticles that decompose pollutants, which include inorganic and organic compounds as well as dangerous pathogens. Recent achievements, outlook, and future directions in the field are discussed. © 2021 The Korean Society of Industrial and Engineering Chemistry
