Abstract
The global epidemic of COVID-19 has intensified the urgency for the development of high-efficiency air filters with antiviral and antibacterial properties. While conventional commercial air purifiers can filter particulate matter, they often fall short of eradicating airborne pathogens. Thus, there is a critical need to innovate air filtration systems capable of not just trapping but exterminating harmful microorganisms to impede their airborne transmission. One potential solution is to use antibacterial photodynamic technique (aPDT). Indeed, recent years have witnessed the rapid growth in this area. This review summaries applications of aPDT for air disinfection through the inactivation of bacteria, fungi, and viruses. In addition, the mechanisms of photosensitizer-assisted pathogen inactivation and the futher development in photodynamic air disinfection technique are also discussed.
期刊介绍：
The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
