A microwave discharge electrodeless lamp (MDEL) was used as the light source for microwave-assisted TiO(2) photo-catalysis to degrade propylene. A MDEL filled with low pressure mercury gas has been developed for the photocatalytic treatment of air pollutants over TiO(2) balls. TiO(2) balls used were produced by the low pressure metal organic chemical vapor deposition method. With increasing microwave power, the degradation efficiency of propylene increased resulting in increased production of CO(2), H(2)O, and CO. It is proposed that propylene is degraded by MDEL and photocatalysts into CH(4) and C(2)H(6), which are then mineralized into CO(2), H(2)O, and CO. C(2)H(2) is suggested to be produced from CH(4) or C(2)H(6) by microwave.
