Cover Story: Acetone, one of the most common VOCs (which are crucial precursors of PM2.5 and ozone) and widely used as an organic solvent, has a pernicious impact on the environment and humans. For catalytic oxidation on acetone removal, inappropriate temperature ranges, more macromolecular byproducts, carbon deposition and SO2/H2O poisoning problems were not resolved. A new type of transition metals (Cr/Fe/Mn/Co)-derived catalysts supported on γ-Al2O3 were prepared and compared for catalytic ozonation of acetone in this study. Results found that CrOx catalysts, bearing abundant Cr6+ and more chemically adsorbed oxygen species Oβ, were originally implied to acetone efficient degradation by catalytic ozonation in low-temperature, SO2/H2O-containing flue gas conditions. Additionally, the acetone catalytic ozonation pathways and sulfur/water poisoning mechanisms were proposed. View this paper
