Investigation on removal of multi-component volatile organic compounds in a two-stage plasma catalytic oxidation system - Comparison of X (X=Cu, Fe, Ce and La) doped MnO catalysts.

MnO-X catalysts (X = Cu, Fe, Ce and La) were prepared based on γ-AlO for the mixture degradation of muti-component volatile organic compounds (VOCs) composed of toluene, acetone, and ethyl acetate. The catalysts were characterized, and the density functional theory (DFT) simulation of ozone adsorption on MnO-X were carried out to investigate the influence of adsorption energy on catalytic performance. The results showed that the removal efficiency (RE) of each VOC component was similarly improved by MnO-X catalysts, and the greatest increase in VOCs' removal efficiency was obtained (7.

Degradation of toluene in surface dielectric barrier discharge (SDBD) reactor with mesh electrode: Synergistic effect of UV and TiO deposited on electrode.

Combing with photo-catalysis and photo-catalyst, a surface dielectric barrier discharge (SDBD) reactor with a mesh electrode was applied for toluene degradation and a high mineralization was achieved. The degradation performance comparison between SDBD reactors with a mesh and a spring electrode was carried out as well. A significant improvement in carbon balance and CO selectivity were obtained in mesh SBDB reactor compared with that of spring's one.

MnO/γ-AlO catalysts synergistic double dielectric barrier discharge (DDBD) degradation of toluene, ethyl-acetate and acetone.

MnO/γ-AlO catalysts was combined with double dielectric barrier discharge (DDBD) for degradation of acetone, toluene and ethyl acetate. MnO/γ-AlO catalysts with different Mn loading were synthesized by hydrothermal method. XRD, SEM, XPS and H-TPR were applied to characterize the catalysts.
