A Novel CFC-12 Hydrolysis Catalyst:WO3/SnO2
摘要:
The catalytic hydrolysis of dichlorodifluoromethane (CFC-12) was investigated over WO3/SnO2 solid acid which was prepared by impregnating Sn(OH)4 with aqueous ammonium metatungstate followed by evaporating, drying and calcining in air. The CFC-12 conversion over WO3/SnO2 at 330℃ remained above 99.5% during 150 h on stream, however, parent metal oxides showed rare catalytic decomposition activity.
