The　removal　of　low　concentrations　of　toluene　using　non-thermal　plasma　(NTP)　coupled　with　Mn-Ce/La/γ-Al2O3　catalysts　was　investigated　in　this　study.　Mn/γ-Al2O3　catalyst,　Mn-Ce/γ-Al2O3　catalyst　and　Mn-La/γ-Al2O3　catalyst　were　prepared　for　the　experiment.　The　removal　efficiency　of　toluene,　generation　of　O3,　COx　selectivity　for　different　reactors　were　studied.　The　catalysts　were　characterized　by　BET,　SEM,　H2-TPR　and　ICP-OES.　The　results　showed　that　the　rare　earth　catalysts　could　effectively　improve　the　removal　efficiency　of　toluene　and　the　degree　of　mineralization.　Mn-La/γ-Al2O3　had　the　better　catalytic　performance　than　Mn-Ce/γ-Al2O3.　The　removal　efficiency　of　toluene　for　the　Mn-La/γ-Al2O3　catalyst　was　72.74%　under　the　initial　concentration　of　toluene　of　600　mg·m-3,　discharge　voltage　of　22　kV　and　gas　flow　rate　of　6　L·min-1.　Moreover,　H2-TPR　results　indicated　that　the　low-temperature　activity　and　capability　of　O3　adsorption　enhanced　with　the　loading　of　rare　earth　catalysts.　The　catalysts　were　contributed　to　the　decomposition　of　O3　and　the　enhancement　of　selectivity　of　CO2　and　COx.　©　All　Right　Reserved.
