Hybrid Ceramic Membrane Catalytic Ozonation

2022
This chapter reviews all applications of (catalytic) ozonation coupled with ceramic membrane without functional surface groups. The combination of ozonation and ceramic membrane shows better potential performance on membrane fouling elimination, which depends on the combination mode, including pre- or in situ ozonation. After that, the ceramic membrane

Recent advances in catalytic decomposition of ozone

Journal of Environmental Sciences, 2020
Ozone (O3), as a harmful air pollutant, has been of wide concern. Safe, efficient, and economical O3 removal methods urgently need to be developed. Catalytic decomposition is the most promising method for O3 removal, especially at room temperature or even subzero temperatures.

Catalytic Ozonation of Sulfosalicylic Acid

Ozone: Science & Engineering, 2002
Abstract The investigation of heterogeneous catalytic ozonation of sulfosalicylic acid (SSal) in aqueous solution is reported in this paper. It was found that catalytic ozonation in the presence of V-O supported on silica gel had a more positive effect on the removal rate (62% in 30 min) of total organic carbon (TOC) than that of ozonation alone (20 ...

Catalytic Ozonation of m-Dinitrobenzene

Ozone: Science & Engineering, 2005
The efficiency of catalytic ozonation with homogeneous (containing dissolved ions of Fe2+, Mn2+, Cu2+, Ni2+, Co2+, V5+, Cr3+, Mo6+) and heterogeneous (MnO2, Ni2O3, Fe2O3, CuO, Al2O3, CoO, V2O5, Cr2O3, MoO3, TiO2) catalysts and non-accompanied ozonation was compared for degradation of m-dinitrobenzene (m-DNB).
