The gamma-AIOOH (boehmite) nanofiber bundles have been synthesized via a convenient quencher method. Most nanofibers contain even smaller nanowires with an average diameter of 5 nm. A series of contrast experiments reveal that the evolvement from nanosheets to nanofibers occurs in the quencher process. gamma-Al2O3 nanofiber bundles with mesoporous character can be obtained by calcining relevant gamma-AlOOH nanostructures at 500 degrees C.
通过一种简便的骤冷法合成了γ -AIOOH（勃姆石）纳米纤维束。大多数纳米纤维包含平均直径为5纳米的甚至更小的纳米线。一系列对比实验表明，在骤冷过程中发生了从纳米片到纳米纤维的演变。通过在500摄氏度下煅烧相关的γ -AlOOH纳米结构，可以获得具有介孔特征的γ -Al2O3纳米纤维束。
