A study on catalytic combustion of chlorobenzenes

VWT and VMoT SCR catalysts have proven to be active in oxidation of chlorobenzenes, while, in the same reaction conditions, polychlorinated compounds formation, although in very low amount, limits the application of Pt–alumina catalyst in chlorinated VOC combustion. Increasing chlorination degree lowers chlorobenzene combustion rate over the most active VWT formulation. IR and activity data indicate that a common reaction mechanism involving as a first step nucleophilic substitution of chlorine atom by lattice oxygen ions occurs over these surfaces.
