Abstract

Heterogeneous catalytic reactions of chlorofluorocarbons (CFCs), like CC12F2 and their substituents, hydrochlorofluorocarbons (HCFCs, for example CHC1F2, are allowed to be used temporarily, until 2030 [1]), are environmentally important problems. Their decomposition or transformation to other valuable compounds could lead to novel technological procedure. Alumina and different zeolites are potential catalysts or supports in these reactions. Solid state NMR techniques (13C, 19F, 29Si, 27A1) proved to be powerful tools to investigate the mechanism of both the surface reaction and the deactivation caused by the reaction between the reactant and the potential catalysts [2,3].
