| 中文摘要: |
| 通过溶剂热法制备了0.5%Pd-5%Cu/MoO3催化剂。评估了双金属负载、单金属负载和无负载催化剂催化苯甲醇氧化的性能，研究了Pd和Cu如何分别促进MoO3基底中的氧原子活化的机理和催化剂复原过程。由于Pd与Cu的协同效应，0.5%Pd-5%Cu/MoO3催化剂具有优异的催化苯甲醇氧化性能，转化率达92.5%，苯甲酸选择性为100%，并在5次循环反应后仍保留了94.3%的活性。 |
| 英文摘要: |
| 0.5%Pd-5%Cu/MoO3 catalyst was prepared by a solvothermal method. The performance of bimetallic, monometallic and unsupported catalysts in catalyzing the oxidation of benzyl alcohol was evaluated, and the mechanism of Pd and Cu involved in promoting oxygen atom activation and the catalyst recovery process in MoO3 were studied. Due to the synergistic effect between Pd and Cu, 0.5%Pd-5%Cu/ MoO3 catalyst has excellent catalytic performance in the oxidation of benzyl alcohol with a conversion of 92.5%, selectivity of 100% for benzoic, and the catalyst still retains 94.3% activity after 5 catalytic cycles. |
