1. A catalyst system comprising:

  • a platinum group metal catalyst bound to a metal oxide support; and

    a crystalline coating of metal oxide nanoparticles selectively disposed on the metal oxide support, wherein the crystalline coating has a porosity of greater than about 20% to less than about 70% and covers greater than or equal to about 1.5% to less than or equal to about 80% of an exposed surface area of the metal oxide support.
