Adopting homogeneous precipitation method,nano-NH4AlO(OH)HCO3 precursor was prepared using NH4Al(SO4)2 and NH4HCO3 as the starting materials. Effects of mixing mode on preparing precursors were identified by XRD,TEM.

• 本文以NH4Al(SO4)2和NH4HCO3为主要原料,采用均相沉淀法制备纳米NH4AlO(OH)HCO3(AACH)先驱体,利用X射线衍射仪和透射电镜研究了滴定方式对其制备的影响。
