Abstract
The catalytic oxidative decomposition of chloropentafluoroethane (CFC- 115) was carried out in the presence of butane with various metal oxid es supported on alumina-zirconia, Tungsten(VI) oxide alone had a posit ive effect on the activity among all the metal oxides. It was conclude d that the active sites of the tungsten(VI) oxide catalyst supported o n alumina-zirconia might be the acid sites formed by the interaction b etween tungsten(VI) oxide and tetragonal zirconia. This catalyst was f ound to be the most active of all the catalysts which have so far been examined, and kept a high activity during the oxidative decomposition of CFC-115 for 25 h.
