摘要：Uniform gamma-AlOOH architectures assembled by nanosheets were successfully synthesized in the mixture of deinonized water and dimethyl sulfoxide (DMSO) at 180 degrees C. The structure and morphology of products were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The products displayed 3D microstructures with its length of 1 mu m and diameter of 400-500 nm. The obtained gamma-AlOOH structures exhibited large Brunauer-Emmett-Teller (BET) surface area of 216.5 m(2)/g and pore size of 3.7 nm. The formation mechanism of 3D gamma-AlOOH architectures was also discussed based on the experimental results. Furthermore, the gamma-AlOOH architectures exhibited preliminary photoluminescence (PL) phenomenon with a strong peak at 323 nm.
