Abstract: Alumina nanowires, amorphous, with diameters from 5 to 15nm, were prepared by catalytic oxidation with mercury as medium. FE-SEM, TEM, EDX, XRD, IR were used to characterize alumina nanowires. With elevation of temperature, oxygen content and purity of aluminium, the alumina nanowires’ specific surface area increases. The concentration of HgCl2 solution and the immersing time of aluminium have no apparent influence on alumina nanowires’ specific surface area.

Key words: alumina, nanowires, mercury, catalytic oxidation
