With the rapid development of industry and economy, the emission of volatile organic compounds (VOCs) is becoming a global focus because of its negative impact on both human health and environment . The combination of cold plasma and catalysis (plasma-catalysis) provides an attractive alternative to the conventional thermal catalytic route for the removal of low concentration of gas pollutants in high volume waste gas streams . Catalyst is a key factor affecting the performance of a plasma-catalytic process . Cu-based catalysts have been investigated in thermal catalytic oxidation of VOCs due to its high catalytic activity and relative low cost. The addition of promoter CeO could further improve the performance for VOC oxidation. However, the use of Cu-Ce catalysts in plasma-catalytic gas cleaning process for the oxidation of VOCs has not been studied before. The synergy resulting from the combination of cold plasma and Cu-Ce catalysts is still not clear.
