Novel clay intercalated metal catalysts: A study of the hydrogenation of styrene and 1-octene on clay intercalated Pd catalysts

摘要: Pd-hexadecylammonium montmorillonite (Pd-HDAM) catalysts have been prepared by a novel synthetic route. Sample characterization including XRD and TEM measurements confirmed the existence of interlayer Pd nanocrystallites which occupy clay particle defect sites. The catalytic activities Pd-HDAM samples were tested hydrogenation 1-octene styrene in liquid phase. reaction was found to be less dependent on dispersion than that 1-octene. highest observed for low medium content. application various solvents made it possible establish correlation between basal spacings dL samples. When value exceeded 3 nm, interlamellar active sites became more accessible reactants.
