A　series　of　experiments　were　performed　for　toluene　decomposition　from　a　gaseous　influent　at　normal　temperature　and　atmospheric　pressure　by　nonthermal　plasma　coupled　with　a　combination　of　catalysts　technology.　Nonthermal　plasma　was　generated　by　dielectric　barrier　discharge.　gamma-Al(2)O(3)　was　used　to　be　a　sorbent　and　a　catalyst　carrier.　Nanocatalysts　were　MnO(2)/gamma-Al(2)O(3)　coupled　with　modified　ferroelectric　of　nano-Ba(0.8)Sr(0.2)Zr(0.1)Ti(0.9)O(3).　gamma-Al(2)O(3)　played　an　important　role　in　prolonging　reaction　time　of　nonthermal　plasma　with　volatile　organic　compounds　molecules.　MnO(2)/gamma-Al(2)O(3)　has　an　advantage　for　ozone　removal,　while　nano-Ba(0.8)Sr(0.2)Zr(0.1)Ti(0.9)O(3)　is　a　kind　of　good　ferroelectric　material　for　improving　energy　efficiency.　Thus　these　packed　materials　were　incorporated　together　to　strengthen　nonthermal　plasma　power　for　volatile　organic　compounds　decomposition.　The　results　showed　the　synergistic　technology　resulted　in　greater　enhancement　of　toluene　removal　and　energy　efficiencies　and　a　better　inhibition　for　ozone　formation　in　the　gas　exhaust.　Based　on　the　data　analysis　of　the　Fourier　transforms　infrared　spectrum,　the　reaction　process　of　toluene　decomposition　and　the　mechanism　of　synergistic　effect　are　discussed.　The　results　showed　in　a　complex　oxidation　mechanism　of　toluene　via　several　pathways,　producing　either　ringretaining　or　ringopening　products.　The　final　products　were　carbon　dioxide　and　water.
