In this work, a simple and economical process, the reduction preparation of the Cu/ZrOCO 3 catalyst and the catalytic transfer hydrogenation (CTH)reaction of methyl levulinate (ML)were carried out simultaneously in one pot providing 89.79% product yield at 180 ° C for 7 h. Different from direct hydrogen transfer reaction catalyzed by ZrOCO 3 with only valerolactone (GVL) produced, the introduction of Cu/Cu + on ZrOCO 3 carrier not only enhances the activity of the reaction, but also further converts GVL into 1,4‐pentanediol (1,4‐PDO)by indirect hydrogen transfer. In addition, we also found the copper‐loaded amphoteric carrier has better catalytic activity than the basic carrier.
