In this work novel Pd supported on cerium oxide nanocomposites in the liquid phase glycerol oxidation with molecular oxygen was studied. Pd/CeO2 and Pd-NiO/CeO2 composites with different Pd loading were prepared using the extractive-pyrolytic method. In the glycerol oxidation processes it was found that Pd/CeO2 and Pd-NiO/CeO2 composites are catalytically active. Besides, NiO additives can significantly increase Pd/CeO2 catalysts’ activity and selectivity to the main product – glyceric acid. Several glycerol oxidation parameters like NaOH initial concentration, glycerol/Pd molar ratio, oxygen pressure and temperature were varied. The best yield of glyceric acid reached 71–75 mol% with full glycerol conversion.
