Tin-119 Miissbuuer spectra show that the cationic oxidation states and crystal structures of some mived oxide catalysts remain unaltered by the adsorption of acidic or basic molecules. Reaction of the oxides with either hydrogen or butenes gives reduced catalysts in which the retention of the tin at

✦ Synopsis
Tin-antimony oxides of the type SnJb,O2 (x = 0.01-0.10) when calcined at 873K form solid solutions in which the Miissbauer parameters steadily depart from those of stannic oxide but provide no evidence for the formation of localised tin(U). Esr measurements indicate the presence of a spin free surface species. Above x = 0.10 a two phase region exists in which the tin rich phase shows constant "'Sn Miissbauer parameters.
