The performance of LNTs is evaluated based on several parameters: - NOx Conversion Efficiency: The percentage of NOx converted to N2 during the lean and rich phases. - Durability: The catalystâs ability to maintain performance over extended periods and under varying conditions. - Thermal Stability: The ability of the catalyst to withstand high temperatures without significant loss of activity. - Resistance to Poisoning: The ability to resist deactivation due to contaminants like sulfur and phosphorus.
