Literature regarding the mechanism of the electrochemical oxidation of aqueous sulfur
dioxide to sulfuric acid has been critically evaluated to provide a detailed understanding of …

Sulfur poisoning is a common problem causing catalyst deactivation during the industrial
catalytic process. However, for selective catalytic reduction of NO x with ammonia (NH3 …

SO2 would deactivate the low-temperature SCR (selective catalytic reduction) catalysts and
reduce NO removal. In this study, Fe (0.1)− Mn (0.4)/TiO2 prepared by sol− gel method was …

Zr is added to the Fe–Mn/Ti catalyst to increase NO conversion and improve SO2 tolerance.
It is found that 0.03 is the optimal ratio for Zr/(Ti+ Zr). With this ratio, the NO conversion below …

The impact of air contaminants such as sulfur compounds (SO2, H2S) and nitrogen
compounds (NOx and NH3) was investigated using subscale fuel cells. The severity of the …

The poisoning of the oxygen-reduction reaction (ORR) by adsorbed sulfur-containing
species was quantified for platinum fuel-cell materials using rotating ring disk electrode …

Sulfur contaminants in air pose a threat to the successful operation of proton exchange
membrane fuel cells (PEMFCs) via poisoning of the Pt-based cathodes. The deactivation …

The different addition amounts of ZrO 2 on CuO-CeO 2/TiO 2 catalyst synthesized by co-
precipitation method were investigated to research the simultaneous removal of Hg 0 and …

SO2 poisoning of catalysts is a prevalent issue in the catalytic combustion of volatile organic
compounds (VOCs), as it can directly impact their conversion efficiency. In this study, we …

Organic pollutants can be effectively degraded by CeO 2/H 2 O 2 system, the catalytic
activity of which is restricted by over-complexation of H 2 O 2 with CeO 2. In this study, nano …
