摘要	Under hydrothermal condition, benefiting from dehydration and in situ nucleation processes, well-crystallized 3-dimensional (3D) boehmite nanoparticles with an average diameter of around 400 nm was directly converted from gibbsite phase in aluminum oxyhydroxide powder without adding any kinds of other assistants. Through investigation the influences of different factors, it is concluded that, hydrothermal treating temperature, time and initial slurry pH play an important role in obtaining well-crystallized boehmite particles. Besides XRD and FE-SEM, TG/DTA, FT-IR and Raman spectra were also employed to follow and confirm the formation of boehmite, which is useful for optimizing the synthesis condition. Moreover, after the hydrothermal treatment under the optimum condition, because as-prepared 3D boehmite nanoparticles have abundant surface oxygen anionic vacancies (F and F+-centers), thus endowing it optical band gap around 5.41 eV. This technique is significant and useful for developing a new opportunity for large scale production of well-crystallized boehmite powder with high purity from aluminum oxyhydroxide powder.
