摘要
总结了 γ-Al2O3载体的常用扩孔方法,主要包括控制前驱物晶粒大小法、模板剂法、添加助剂法或扩孔剂法,以及其他方法,如水热处理法和低温烧结法,并结合具体实例,指出了上述各扩孔方法的优点和存在的局限性,展望了未来制备大孔γ-Al2O3载体的研究方向.
Abstract
The commonly used pore-expanding methods for γ-Al2O3 carrier are summarized,which mainly include controlling the crystal particle size of precursor,template method,adding additives or pore-expanding agent,and other methods,such as hydrothermal treatment and low-temperature sintering.Combined with the specific examples,the advantages and limitations of each of the above pore-expanding methods are pointed out,and the research direction for the future preparation of macroporous γ-Al2O3 carriers is prospected.
