Synthesis and Characterization of Ni/Al₂O₃ Nanocomposite for Selective Reduction of Aliphatic Double Bond(s)

Abstract:

Ni nanoparticles dispersed in Al2O3 are prepared in-situ by the reduction of Ni(acac)2 under steady stream of [H2Al(OtBu)]2 in a cold walled CVD reactor. The decomposition temperature is moderate (~500°C) and the by-products are removed as soon as produced. The resulting powder of Ni/Al2O3 nanocomposite is characterized by powder XRD giving diffraction pattern for metallic Ni only. Elemental composition of the powder is confirmed by EDX analysis. SEM and TEM are used for the study of morphology and particle size determination. The aliphatic double bond in 1,2-trans-diphenylethene is reduced under hydrogen environment using the as prepared Ni/Al2O3 nanocomposite as catalyst. The reduction of 1,2-trans-diphenylethene is carried out at low temperature (~80°C) and atmospheric hydrogen pressure. The hydrogenation of aliphatic double bond is followed by IR and NMR spectroscopy.
