Hydrous zirconia supported ruthenium catalyst Ru/ZrO 2 · x H 2 O, prepared by co‐precipitating ruthenium trichloride and zirconium oxychloride with ammonia, was able to catalyze efficiently methyl propionate to propanol under the mild conditions. In aqueous system, the propanol yield of >99% was achieved under the conditions of reaction temperature of 150°C and hydrogen pressure of 5.0 MPa, while in non‐aqueous system the maximum propanol yield was only 47.0%. FTIR spectra and hydrogenation results indicated that the high catalytic performance of Ru/ZrO 2 · x H 2 O in aqueous phase results from the cooperation effect between water as a solvent and hydroxyl groups on the surface of carrier.
