Non-thermal plasma and modified catalysts: A synergistic approach to air purification

Abstract

With the increasing air pollutants that threaten human health, the quest for innovative air purification solutions has been more critical. This review delves into the frontier of NTP and modified catalysts, offering a compelling approach to air purification. Traditional catalysts, despite their pivotal role, generally falter in the face of deactivation, poisoning, and stability issues. With the advantage of generating reactive particles, NTP outstandingly promotes the catalytic process, contributing to the reinforced pollutant degradation efficiency and catalytic conversion rates. This review elucidates the fundamental principles of NTP, its impact on catalyst modification, and the structural and chemical changes it induces. Additionally, the mechanisms and advancements of the NTP-catalyst system are also illuminated. This system is identified as a hopeful path for air purification and environmental protection attributed to its improved energy efficiency, low-temperature operation, and significant reduction in harmful by-products. Moreover, challenges and perspectives are presented for the further optimal combination of NTP with catalysts and broadening their practical applications.
