Deterioration analysis of real-world scr catalysts in diesel vehicles

HIGHLIGHTS

• What: This study reveals that the accumulation of chemical poisons is the primary reason for the deterioration of Cu-SSZ-13 in real-world conditions. The aim of this research is to investigate the poisoning of catalysts at the atomic level during operation in real-world and to provide theoretical guidance for policy formulation and emission control strategies. Temperature-programmed desorption (TPD) experiments were conducted to investigate the content of surface adsorbed species on the catalyst samples.
• Who: Tongliang Zhang 1 and colleagues from the School of Rare Earths, University of Science and Technology of . . .
