Abstract
Recently, a VOCs/odor control technology using nonthermal plasma has been installed in waste-water treatment plants, food process industries, etc., and its share in Japan increases gradually according to the marketing research. However, its application field is very much limited because the removal performance for high concentration VOCs are insufficient. The plasma-catalyst systems have been studied by many researchers in order to overcome these problems. Although the effectiveness of catalysts in plasma systems has been reported, the reaction mechanisms and the role of solid surfaces are not well understood. In this review, I summarize the significant role of solid surfaces under plasma discharge from recent papers. The relationship between solid surfaces and active species derived by plasma discharge is also discussed based on our research results.
