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
