From sheets to fibers: A novel approach to gamma-AlOOH and gamma-A12O3 1D nanostructures.
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.
