Catalytic oxidation of volatile organic compounds by plasma–metal oxide coupling

Abstract

This review summarizes the plasma-assisted catalytic removal of volatile organic compounds (VOCs) over metal oxide-based catalysts. Apart from the fundamental working processes and classifications of non-thermal plasma, reaction mechanisms, combination configurations and operation modes in catalyst-plasma hybrid systems, the main contents refer to the applications of metal oxides as catalysts for the plasma catalysis of VOCs. In this part, the catalyst–plasma synergy and structure–performance relationship are discussed in depth by referring to specific examples of VOC abatement. After that, a comprehensive coverage of parameter effects is critically demonstrated, followed by the illustration of advanced reactor design. Finally, conclusive remarks and future prospects are proposed.
