Photodegradation of chlorofluorocarbon alternatives on metal oxide
Abstract
HCFC and HFC were photodegraded on metal oxides. Degradation rate on several metal oxides was in the order: TiO[sub 2] > ZnO > Fe[sub 2]O[sub 3] > kaolin [ge] SiO[sub 2] [ge] Al[sub 2]O[sub 3]. Principal degradation products were CO[sub 2], Cl[sup [minus]] and F[sup [minus]]. Minor products which oxidize I[sup [minus]] were included for some HCFC's. A photocatalytic process is suggested for the degradation reaction. An overall reaction equation is proposed on the basis of mass balance.
