Abstract: A process of a catalytic combustion is disclosed. The process can be started at a cold temperature and then raised to a desired high temperature in a very short time by employing a noble metal catalyst dispersed on a supporting material. Moreover, a method for dispersing a noble metal catalyst used in the catalytic combustion is also disclosed for increasing a specific surface area of the catalyst so as to facilitate the catalytic combustion. Furthermore, a substance including a promoter dispersing a metal catalyst therewith, and a supporting material supporting the promoter with the metal catalyst is also disclosed, so that a contact surface area of the metal catalyst can be increased, thereby the catalytic combustion can be initiated within a very short period.

Moreover, a method for dispersing a noble metal catalyst used in the catalytic combustion is also disclosed for increasing a specific surface area of the catalyst so as to facilitate the catalytic combustion. Furthermore, a substance including a boron nitride supported noble metal catalyst, a substrate for suspending the catalyst, and a supporting material for dispersing the substrate with said catalyst is also disclosed so that a total surface area of the catalyst can be increased, thereby the catalytic combustion can be initiated in a very short time.
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 m2/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.
