The one-step synthesis of methyl isobutyl ketone from acetone (MIBK) and H2 in liquid phase was studied over Ni-zirconia catalyst prepared by precipitation. The performances of Ni/ZrO2 catalysts were evaluated by the conversion of acetone and the selectivity of MIBK. The effect of different preparation conditions such as aging temperature, calcination temperature, nickel content and reduction temperature was investigated. The results showed that high acetone conversions of up to 33% and MIBK selectivities of up to 85% were recorded at a nickel content of 13.0 wt % and the reduction temperature of 400°C.

Four different metal nanoparticles (metal = Ag, Ru, Pt, or Rh) were impregnated on the acidic cesium salt of tungstophosphoric acid Cs2.5H0.5PW12O40 (CsPW) with a loading amount of 2 wt%. The prepared catalysts were characterized by using X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), N2 sorption measurements, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). Results confirmed the formation of highly distributed metallic nanoparticle centres over the acidic CsPW. The catalytic activity of the prepared catalysts were evaluated in the liquid phase hydrogenation of methyl isobutyl ketone (MIBK) to 2-methylpentane (2-MP) at 453 K. Pd-CsPW showed the highest activity compared to other catalysts, where 10% conversion was obtained with 91% selectivity after 4 h’s reaction time.
