Promotional effect of ion-exchanged K on the low-temperature hydrothermal stability of Cu/SAPO-34 and its synergic application with Fe/Beta catalysts

Chen Wang et al.

Summary: The introduction of potassium ions into Cu/SAPO-34 catalysts via ion exchange improves their stability during low-temperature hydrothermal aging. The catalysts with potassium loading exhibit improved structure, acidity, and active site conservation after hydrothermal aging. A combined system of Fe/Beta and potassium-loaded Cu/SAPO-34 catalysts shows potential for NO(x) elimination in real-world applications.

PM-support interfacial effect and oxygen mobility in Pt, Pd or Rh-loaded (Ce,Zr,La)O2 catalysts

Ting Wang et al.

Summary: The physicochemical properties and catalytic performances of Pt/CZL, Pd/CZL, and Rh/CZL catalysts were systematically characterized to illustrate the relationship between their dynamic oxygen storage/release capacity, redox ability, and catalytic activities for HC, NOx, and CO conversions. The study found that Pt/CZL exhibited the best catalytic performance for HC and NOx elimination due to its excellent redox ability and dynamic oxygen storage/release capacity, while Pd/CZL showed higher catalytic activity for CO conversion and Rh/CZL had the widest dynamic operation window for NOx elimination.

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.
