A series of CuO/SiO 2 catalysts containing different modifiers were prepared via co‐precipitation and used for glycerol hydrogenolysis. CuO–CeO 2 /SiO 2 gave the best glycerol conversion rate (100%) and highest selectivity for 1,2‐propanediol (up to 95%). Reactions were carried out under the following conditions: temperature, 220°C; H 2 pressure, 0.5 MPa; glycerol concentration, 100 wt.%; and H 2 /glycerol molar ratio, 35:1. The catalysts were characterised by X‐ray diffraction, NH 3 temperature‐programmed desorption, N 2 adsorption, and scanning electron microscopy. The CuO–CeO 2 /SiO 2 catalyst had smaller particle sizes, better dispersion, and greater specific surface area than the CuO/SiO 2 , CuO–phosphotungstic acid (PTA)/SiO 2 , and CuO–CeO 2 –PTA/SiO 2 catalysts.
