摘要：

The catalytic oxidative decomposition of chloropentafluoroethane (CFC-115) was carried out in the presence of butane with various metal oxides supported on alumina-zirconia, Tungsten(VI) oxide alone had a positive effect on the activity among all the metal oxides. It was concluded that the active sites of the tungsten(VI) oxide catalyst supported on alumina-zirconia might be the acid sites formed by the interaction between tungsten(VI) oxide and tetragonal zirconia. This catalyst was found 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.
