N2 - Destruction of indoor air pollutant formaldehyde using dielectric barrier discharge plasma in a coaxial cylindrical reactor was carried out at atmospheric pressure and room temperature. Three kinds of catalysts, that is, TiO 2, BaTiO3, or TiO2 & BaTiO3 were tested for HCHO removal. Effect of catalyst carrier, catalysts, and catalyst amount on specific energy density (SED), energy yield (EY) and HCHO removal efficiency were investigated. The byproduct was detected and the mechanism of HCHO degradation was performed. It had been found that DBD reactor contained TiO2 & BaTiO3 catalysts could effectively decompose formaldehyde. The HCHO conversion of three kinds of catalyst was TiO2 & BaTiO3 > BaTiO3 > TiO2. Higher amount of BaTiO3 in TiO2 & BaTiO3 catalysts was slightly superior to the smaller. Furthermore, TiO2 & BaTiO3 catalyst could not only enhance the HCHO removal efficiency, but also save the energy, which could be used for industrial application.
