A　series　of　experiments　using　non-thermal　plasma　coupled　with　catalyst　for　toluene　removal　were　carried　out.　Based　on　reactor　input　energy　density　and　removal　efficiency　and　energy　efficiency　and　inhibition　for　O3　formation,　catalyst　load　amount　on　the　surface　of　γ-Al2O3　pellets　and　the　performance　of　different　catalysts　were　compared　in　the　experiments.　The　results　show　the　catalysis　performance　of　10%　MnOx/γ-Al2O3　coupled　with　non-thermal　plasma　was　highest.　Nano-TiO2/γ-Al2O3　and　MnOx/γ-Al2O3　catalysts　coupled　with　non-thermal　plasma　resulted　in　greater　enhancement　of　toluene　removal　efficiency　and　energy　efficiency.　MnOx/γ-Al2O3　operated　on　a　better　inhibition　for　O3　formation　in　the　gas　exhaust.
