| Abstract: | PASCA has been used to search for evidence on different types of sites existing on alumina surfaces. The results indicate that PtCl62– interacts with different surface sites, forming MSI complexes PtOxCly–Sk, PtOxCly–Ss and PtOxCly–St. Surface sites in different aluminas may be different in chemical and electronic properties.
