Abstract
A catalytic converter includes a catalyst. The catalyst includes a support, platinum group metal (PGM) particles dispersed on the support, and metal oxide nanoparticles formed on the support. The metal oxide nanoparticles are dispersed between a first set of the PGM particles and a second set of the PGM particles to suppress aging of the PGM particles.
