摘　　要：介绍了γ-Al2O3作为催化剂载体的优点和最新研究进展,同时介绍了超声波在化学合成领域中的发展过程以及超声波在γ-Al2O3载体制备过程中的作用机理。经过不同超声波反应条件制备的γ-Al2O3载体,其团聚程度,孔结构等性质均会发生不同程度的变化,能够对所制备载体的性质起到优化作用,从而提高催化剂的性能。Abstract： Advantages ofγ-AI2O3 as catalyst carrier were introduced as well as its latest research progress. Application of ultrasonic wave in the field of chemical synthesis was described as well as the function mechanism of ultrasonic in preparation process of γ-AI2O3, γ-AI2O3 carriers which were synthesized in different ultrasonic reaction conditions had different degrees of change in agglomeration and pore structure. The ultrasonic can optimize the properties of the γ-AI2O3 carrier, and improve the performance of catalyst.
