In　this　paper,　we　report　toluene　destruction　using　a　spontaneous　polarization　plasma　and　photocatalyst　reactor　in　air　at　atmospheric　pressure　and　room　temperature.　A　spontaneous　polarization　material　(BaTiO3)　and　photocatalyst　(TiO2)　were　added　to　the　plasma　system　simultaneously.　Three　types　of　catalyst,　i.e.,　TiO2,　BaTiO3,　or　TiO2/BaTiO3,　were　used　for　toluene　removal.　The　catalyst　carrier,　type,　and　amount　were　important　factors　in　the　toluene　removal　efficiency.　The　specific　energy　density　and　energy　yield　during　the　discharge　process　were　investigated.　The　toluene　removal　efficiency　increased　when　a　spontaneous　polarization　plasma　was　combined　with　the　photocatalyst.　In　terms　of　toluene　removal　efficiency,　the　activity　order　was　TiO2/BaTiO3　＞　BaTiO3　＞　TiO2　＞　none.　Large　amounts　of　BaTiO3　in　the　TiO2/BaTiO3　catalyst　gave　slightly　better　conversion.　The　TiO2/BaTiO3　catalyst,　not　only　enhanced　the　toluene　removal　efficiency,　but　also　saved　energy,　making　it　useful　for　industrial　applications.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
