In one embodiment, an oxidation catalyst comprises a catalytic material disposed on a support. The support comprises boron modified alumina and about 10 wt % to about 50 wt % zeolite, based upon the total weight of the support. The boron is present in a sufficient amount up to less than or equal to about 7 wt %, based upon a total weight of the alumina, to selectively poison a portion of the alumina.
