Abstract

The oxidative decomposition of dichlorodifluoromethane (CFC-12) over tungsten(VI) oxide-loaded alumina-zirconia at low temperature has been investigated. Oxidative decomposition in air was found achieve higher initial CFC-12 conversion rates than hydrolysis and oxidative decomposition in the presence of water or butane, although the conversion rate decreased markedly with time on stream. Loading the alumina-zirconia support with platinum-group metals results in higher sustained activity, and the addition of platinum in particular allows initial conversion rate to be maintained for at least 4 h on stream.
