Disclosed herein are monolith oxidation catalysts for the destruction of CO and volatile organic compounds (VOC) chemical emissions, in particular, the destruction of light alkane organic compounds. The catalysts contain high surface area refractory oxides of silica- and hafnia-doped zirconia and silica, or tin oxide or stabilized alumina; and at least one platinum group metals, in particular platinum metal, or a combination of platinum and palladium.

Oxidation catalysts for destructing VOCs which contain light alkane compounds in emissions

A diesel oxidation catalyst comprising a honeycomb substrate washcoated with a mixture of clay, a refractory oxide and a zeolite is disclosed. The washcoated substrate is subsequently deposited with a precious metal catalyst and a sulfur oxidation suppressant. In a preferred embodiment, the clay is acid-leached bentonite, the refractory oxide is zirconia or titania, the zeolite is beta-zeolite or Y-zeolite or ZSM-5 or mordenite, the precious metal catalyst is preferably platinum, and the sulfur oxidation suppressant is vanadium or vanadium oxide or a combination thereof
