Sulfur-resistance iron catalyst in sulfur-containing VOCs abatement modulated through H2 reduction

Enhanced sulfur resistance by constructing MnOx–Co3O4 interface on Ni foam in the removal of benzene

“…19,20 To improve SO 2 -tolerance, one strategy is to regulate the surface electronic properties of catalysts; the other approach is to introduce an active phase as a scavenger to preferentially capture SO 2 . 21,22 Xu et al revealed that V doping into a 13Cu/γ-Al 2 O 3 catalyst exhibited acceptable SO 2 resistance of the 13Cu/γ-Al 2 O 3 catalyst for toluene oxidation owing to the synergy between Cu and V oxide. 23 Deng et al confirmed that a W-doped Pt/TiO 2 catalyst could inhibit SO 2 adsorption and activity, thus improving SO 2 resistance for acetone oxidation.…”
