以十八水合硫酸铝和尿素为原料,十六烷基三甲基溴化铵(CTAB)和酒石酸钠为表面活性剂,在165℃水热条件下反应3 h,制备花状γ-AlOOH 结构。采用扫描电镜(SEM )、热重分析和 X 射线衍射(XRD)对样品进行表征。实验结果表明,采用水热法可以得到长度、厚度均匀的γ-AlOOH 纳米片组装成的花状γ-AlOOH。
The flower-likeγ-AlOOH was successfully prepared via hydrothermal method at 165 ℃ for 3 h,by u-sing Al2(SO4)3·18H2O and urea as raw materials,CTAB and sodium tartrate as surfactants.The as-prepared products were characterized by SEM,XRD and TGA.The experimental results show that the as-synthesized flower-likeγ-AlOOH with a diameter of about 4μm was composed of uniform nanosheets.
