Abstract
This work reports the formation of some new non-classical carbonyls of platinum formed after CO adsorption on Pt-H-ZSM-5. These are: (i) Pt3+(CO)2 dicarbonyls (2211 and 2175Â cmâ1), which are decomposed without producing monocarbonyls; (ii) Pt2+(CO)2 (2165 and 2150Â cmâ1), decomposed via Pt2+-CO species (2113Â cmâ1); and (iii) Pt+(CO)3 complexes (2162, 2150 and 2110Â cmâ1) which easily loose one CO ligand even at room temperature being thus converted to Pt+(CO)2 (2120 and 2091Â cmâ1). The latter are thermally decomposed without producing monocarbonyls.
