The comprehensive review of catalysts for catalytic oxidation of volatile organic compounds

Abstract

Volatile organic compounds (VOCs) are an important factor contributing to air pollution and have received significant attention due to their toxicity and severe impact on the environment and human health. Catalytic oxidation technology has been widely recognized as an effective end-of-pipe control method for VOCs, which has been extensively studied in recent years to enhance catalyst activity, stability, and economic benefits. So, this review focuses on summarizing noble metal catalysts, non-noble metal and composite catalysts used in VOCs catalytic oxidation; analyzing factors influencing their catalytic activity and improvement methods; objectively evaluating the catalytic performance and key parameters of these catalysts; discussing the catalytic oxidation mechanism. Based on this comprehensive review, the development routes and strategies of catalysts preparing for VOC catalytic oxidation will be more explicit, while their application scenarios and parameters will be clearer.
