Combined　with　NTP,　catalysis　and　reverse-flow　technology,　the　effects　on　the　temperature　rise　(T),　specific　energy　density　(SED)　and　energy　efficiency　(EE)　of　the　system　were　investigated　under　the　influence　of　different　reaction　system　(grounding　mode,　wall　thickness)　and　power　supply　(voltage　and　frequency).　The　effects　of　toluene　removal　(η)　and　products　were　also　analyzed.　The　results　showed　that　the　reverse　flow　non-thermal　plasma-catalytic　reaction　system　had　the　best　η　and　EE,　which　was　3.76g/(kW•h).　The　differences　in　T　under　three　grounding　conditions　were　not　significant　when　voltage　was　increased　continuously.　The　concentrations　of　O3,　η,　SED　and　EE　were　the　highest　when　the　aluminum　foil　was　grounded.　The　T,　η,　SED　and　EE　decreased　with　the　increase　of　wall　thickness.　When　three　technologies　were　combined,　NO2　was　less　generated,　fewer　types　of　organic　by-products　were　produced,　the　CO2　selectivity　was　high　and　the　toluene　mineralization　rate　were　highest.　When　the　frequency　was　fixed,　the　T,　η,　SED　were　positively　proportional　to　the　voltage　as　voltage　increased,　while　the　EE　showed　the　opposite　correlation　with　voltage.　When　aluminum　foil　was　grounded,　the　T　achieved　110.7　and　the　η　was　74.05%.　The　concentration　of　the　byproduct　(O3)　increased　in　the　beginning,　then　decreased,　and　finally　became　0mg/m3.　When　the　frequency　changed　while　the　voltage　was　fixed,　the　change　rules　were　the　same.　©　2019,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
