    Effect of Tin Precursor on the Catalytic Properties of Pt-Sn/Al2O3 Sol-Gel Prepared Catalysts (1997)
    Springer
    Journal of sol gel science and technology 8 (1997), S. 847-849 
    Details
    ISSN: 1573-4846
    Keywords: platinum-tin catalysts ; Pt-Sn sol-gel catalysts ; cyclohexane dehydrogenation ; n-hexane conversion
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Tin-alumina supports were prepared by cogelation of aluminum tri-sec-butoxide and tetrabutyltin or tin tetrachloride. Aqueous or acetone platinum solutions were used for impregnation. The results show that the specific surface area and the acidity of the catalysts were only slightly modified by the metal precursors used. On cyclohexane dehydrogenation and n-hexane conversion, high selectivity to olefins and low cracking products were detected.

    Pt-Sn/Al2O3 sol-gel catalysts: Metallic phase characterization (1993)
    Springer
    Catalysis letters 21 (1993), S. 309-320 
    Details
    ISSN: 1572-879X
    Keywords: Sol-gel catalysts ; platinum-tin catalysts ; platinum dispersion ; X-ray diffraction ; energy dispersive X-ray analysis ; EDX analysis

    Topics: Chemistry and Pharmacology
    Notes: Abstract Highly dispersed platinum was found in Pt-Sn/Al2O3 catalysts prepared by the sol-gel method, i.e., cogelation of aluminum tri-sec-butoxide and tetrabutyltin and subsequent impregnation with hexachloroplatinic acid. X-ray diffraction studies showed that the cell parameter of pure platinum is not modified in bimetallic Pt-Sn samples. Moreover, energy dispersive X-ray analysis studies (EDX) showed that platinum, but not tin, was detected in the catalysts where tin was incorporated by the sol-gel coprecipitation of tin and aluminum. Incorporation of tin into the alumina network is suggested.
