Synthesis of Nio-nanoparticles on nanoporous clay matrix and catalytic transfer hydrogenation reaction.
Applied Clay Science, 53.
pp. 650-656.
Abstract
Ni°-nanoparticles of 0–8 nm were prepared in situ by impregnation of Ni(CH3COO)2 into the nanopores of
modifiedmontmorillonite(Mt)followedbypolyolreduction.TheMtwasactivatedwithHClundercontrolled
condition for generating desired pore sizes. The porous materials were characterized by XRD, TEM, SEM,
UV–visible spectroscopy, FTIR and XPS analysis. N2 adsorption data revealed specific surface areas (BET) in
the range of 296–548 m2/g, specific pore volumes of 0.4–0.6 cm3/g and pore diameters of 0–6.8 nm.
XRD pattern of Ni°-nanoparticles revealed the formation of face centered cubic (fcc) lattice. These supported
Nio-nanoparticles show efficient catalytic activity in transfer hydrogenation of acetophenone to 1phenylethanol
with about 98% conversion, having nearly 100% selectivit
