Development of metal oxide catalysts for the removal of VOCs

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 deg C) due to the surface exposed metallic Ag deg. However,when the catalyst was calcined at higher temperature (800 deg C),it became less active since Ag deg was changed into Ag~+ ion to form Ag_2MnO_4.
