Studies of sulfur poisoning process via ammonium sulfate on MnO2/γ-Al2O3 catalyst for catalytic combustion of toluene

Zhuo Wang et al.

Summary: In this study, MnO2/gamma-Al2O3 catalysts were quantitatively sulfur-poisoned using (NH4)(2)SO4, leading to a significant decrease in catalytic activity depending on the amount of (NH4)(2)SO4. Characterization results confirmed the stability of the catalyst structure when (NH4)(2)SO4 was used, but the declined activity was attributed to the adsorption and occupation of sulfur species on active sites, as well as the formation of inactive sulfate species via further oxidation. This work exemplifies a promising strategy for evaluating sulfur-poisoning deactivation of catalysts for VOCs combustion.

Insight into the SO2 resistance mechanism on γ-Fe2O3 catalyst in NH3-SCR reaction: A collaborated experimental and DFT study

Yaxin Yu et al.

Summary: Research has shown that SO2 poisoning of NH3-SCR catalysts at low temperature remains a challenge. The formation of sulfate species inhibits the adsorption of NOx, while the formation of ferric sulfate enhances surface acidity, leading to an increase in catalytic activity.

Synthesis, characterization and catalytic activity of cryptomelane/montmorillonite composites

L. Vaculikova et al.

Summary: Manganese oxides are effective catalysts for the oxidation of VOCs, and MnO2/montmorillonite composites were prepared and characterized. The composites showed higher activity in toluene oxidation and the catalytic performance in ethanol combustion was influenced by the distribution of potassium between montmorillonites and cryptomelane.

Facile homogeneous precipitation method to prepare MnO2 with high performance in catalytic oxidation of ethyl acetate

Tingting Pan et al.

Summary: A facile homogeneous precipitation method driven by synchronous reactions of urea hydrolysis and potassium permanganate reduction was proposed for preparation of α-MnO2 catalysts. Different morphologies of pure α-MnO2 nanostructures were obtained by tuning the precipitation conditions. The physiochemical properties of the catalysts were significantly influenced by the precipitation temperature and time.

Oxygen vacancy induced MnO2 catalysts for efficient toluene catalytic oxidation

Jia Zeng et al.

Summary: This study demonstrates the tuning of oxygen vacancies on alpha-MnO2 for catalytic toluene oxidation, resulting in superior activity and stability. The control of oxygen vacancies weakens the Mn-O bond strength, increases the amount of surface adsorbed active oxygen species, and promotes catalytic activity.
