Abstract
A noble metal catalyst supported on boron nitride (BN) is used for the deep oxidation of organic compounds. The superior activity of the catalyst provides an extreme low light-off temperature and a short induction period at the deep oxidation reaction of organic compounds in air stream. The catalyst outperforms the traditional oxide-supported Pt catalysts with respect to the life and activity. The specific surface area of BN ranges from 1 to 100 m.sup.2 /g, and the loading of the noble metal is in the range of 0.1 to 5.0 wt %. The noble metal can be selected from a group consisting of platinum (Pt), palladium (Pd), rhodium (Rh), Ruthenium (Ru) and a mixture thereof.
