%X A series of CeO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub>, CeO<sub>2</sub>-TiO<sub>2</sub>, CeO<sub>2</sub>-ZrO<sub>2</sub>, and CeO<sub>2</sub>-SiO<sub>2</sub> mixed-oxide supported copper catalysts were prepared by a modified deposition-precipitation method from ultra dilute aqueous solutions and were investigated for hydrogenolysis of cellulose in aqueous medium, in the presence of hydrogen to produce sorbitol as major product. Among all the catalysts tested in the present work, CuO/CeO&lt;sub&gt;2&lt;/sub&gt;ZrO&lt;sub&gt;2&lt;/sub&gt;&nbsp;catalyst proved to be the most promising with high conversion (92%) and excellent selectivity (sorbitol 99.1%), at an intermediate reaction temperature of 245ˇăC in a neutral aqueous solution without an aid of liquid phase acid. The catalyst was recyclable in repeated runs and no deactivation was observed even after five reaction cycles. CuO/CeO<sub>2</sub>-ZrO<sub>2</sub> has been characterized by XRD, SEM, TPR and BET surface area techniques.
