The optimizing utilization of carbon resources has drawn wide attention all over the world,while exploit-ing the high-efficiency catalytic routes remains a challenge.Here,a direct methanol synthesis route is realized from pure CO and H2O over 10％Cu/t-ZrO2 catalyst,where the time yield of methanol is 144.43 mmol molCu-1 h-1 and the methanol selectivity in hydrocarbons is 100％.The Cu species highly dispersed in the t-ZrO2 support lead parts of them in the cationic state.The Cu+sites contribute to the dissociation of H2O,providing the H*source for methanol synthesis,while the formed Cu0 sites promote the absorption and transfer of H*during the reaction.Moreover,the H2O is even a better H resource than H2 due to its better dissociation effectivity in this catalytic system.The present work offers a new approach for methanol synthesis from CO and new insight into the process of supplying H donor.
