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

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.
