PASCA,in conjunction with IR and chemical analysis,has been used to study Al₂O₃ and Pt/Al₂O₃ catalytic systems with and without chlorine.In the absence of Cl^- ions,Pt,can not interact with any surface sites of Al₂O₃.This indicates that Cl^- ions play a very important role in the interaction between the metal (Pt) and its support (All₂O₃).Platinum,in form of [PtCl₆]⁼,interacts with the surface sites of Al₂O₃ by replacing the hydroxyls (OH^-) from the surface,resulting in the formation of MSIC (metal-support interaction complex).
