The hydrodeoxygenation of methyl isobutyl ketone (MIBK) to give 2-methylpentane (2MP) in the liquid phase proceeds with high selectivity on bifunctional catalysts containing Pt nanoparticles and a Keggin heteropoly acid. This reaction was found to proceed most efficiently on a catalyst with 1% Pt and 25% H3PW12O40 on SiO2 (Pt/HPW/SiO2) at 170 °C to give 2MP with 73% selectivity and 52% conversion of MIBK, which is much higher than the efficiency of the previously described catalyst Pt/Cs2.5H0.5PW12O40 in the liquid phase.
