摘要

Metal oxide catalysts were tested for the removal of volatile organic compounds (VOCs) in an atmospheric fixed bed flow reactor. Silver containing mixed oxide was highly active when it was calcined at lower temperature (400 °C) due to the surface exposed metallic Ag°. However, when the catalyst was calcined at higher temperature (800 °C), it became less active since Ag° was changed into Ag~+ ion to form Ag_2MnO_4. The complete oxidation of various VOCs by this catalyst took place at 270 °C, which is 80～180 °C lower than the literature values. Therefore, mixed metal oxide seems to be substituted for noble metal catalysts for the economic removal of VOCs.
