Key Points

Sulfur poisoning affects copper migration and agglomeration during aging, impacting SCR performance.
A change in sulfur resistance of copper sites is observed due to hydrothermal aging processes.
This coupling mechanism highlights the intricate relationship between sulfur and thermal stability of catalysts.
Understanding these interactions may enhance SCR catalyst durability in real-world applications.

Implication

Experimental investigation shows how sulfur poisoning alters copper migration in SCR catalysts, suggesting complex aging effects.

Abstract

Sulfur poisoning influences copper migration and copper agglomeration during hydrothermal aging, while hydrothermal aging alters the sulfur resistance of copper sites through copper migration.
