Abstract: An inorganic oxide material doped with nano-rare earth oxide particles that is capable of trapping one or more of NOx or SOx at a temperature that is less than 400° C. The nano-rare earth oxide particles have a particle size that is less than 10 nanometers. The catalyst support can trap at least 0.5% NO2 at a temperature less than 350° C. and/or at least 0.4% SO2 at a temperature less than 325° C. The catalyst support can trap at least 0.5% NO2 and/or at least 0.2% SO2 at a temperature that is less than 250° C. after being aged at 800° C. for 16 hours in a 10% steam environment. The catalyst support exhibits at least a 25% increase in capacity for at least one of NOx or SOx trapping at a temperature that is less than 400° C. when compared to a conventional rare earth doped support in a 10% steam environment.
