分别以硫酸铝和尿素为铝源和沉淀剂，采用TritonX-100辅助水热法合成了具有分级结构的海胆状勃姆石和氧化铝空心微球。采用X射线衍射（XRD）、热重分析（TG）、傅里叶变换红外光谱（FT-IR）、扫描电镜（SEM）、透射电镜（TEM）和N2吸附-脱附技术对样品进行了表征。SEM和TEM证实了所制备的样品具有多级有序的海胆状中空结构，针状物长度约为1 μm。通过调节Triton X-100的浓度，可以方便地控制勃姆石和氧化铝的形貌和结构。在CTX = 0.01 M时，获得了具有146.91 m2 g-1的大SBET值、0.92 cm 3 g-1的孔体积和分级结构的海胆状氧化铝。此外，还提出了一种可能的机制，为形成这种分级组织的海胆状勃姆石。
Hierarchically organized urchin-like hollow boehmite and alumina microspheres were successfully synthesized via a facile tert-octyl-phenyl polyoxyethylene ether (Triton X-100) assisted hydrothermal route using aluminum sulfate and urea as an aluminum source and a precipitant, respectively. The samples were characterized by X-ray diffraction (XRD), thermogravimetry (TG), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2 adsorption–desorption technique. SEM and TEM verified the hierarchically organized urchin-like hollow structure of the as-prepared samples with needles of about 1 μm length. The morphology and textual structure of boehmite and alumina can be handily controlled by adjusting the concentration of Triton X-100. Urchin-like alumina with a large SBET value of 146.91 m2 g−1, a pore volume of 0.92 cm3 g−1 and a hierarchical structure was obtained at CTX = 0.01 M. Furthermore, a possible mechanism was also proposed for the formation of this hierarchically organized urchin-like boehmite.
