- •
Catalysts with high Mn content exhibit high activity for CB combustion.
- •
For all Mn–CeLa catalysts, deactivation due to Cl adsorption is observed.
- •
Cl species can be removed through Deacon reaction and hydrolysis, respectively.
- •
At 330 °C or higher temperature, all catalysts present stable activity.
- •
High activity for Deacon reaction is critical to inhibit the deposition of Cl.
