Resumo
We proposed here a new process coupling dielectric barrier discharge (DBD) plasma with magnetic photocatalytic material nanoparticles for improving yield in DBD degradation of methyl orange (MO). TiO2 doped Fe3O4 (TiO2/Fe3O4) was prepared by the sol-gel method and used as a new type of magnetic photocatalyst in DBD system. It was found that the introduction of TiO2/Fe3O4 in DBD system could effectively make use of the energy generated in DBD process and improve hydroxyl radical contributed by the main surface Fenton reaction, photocatalytic reaction and catalytic decomposition of dissolved ozone. Most part of MO (88%) was degraded during 30 min at peak voltage of 13 kV and TiO2/Fe3O4 load of 100 mg/L, with a rate constant of 0.0731 min−1 and a degradation yield of 7.23 g/(kW h). The coupled system showed higher degradation efficiency for MO removal.
