Fabrication of boehmite AlOOH and gamma-Al2O3 nanotubes via a soft solution route

The tubular form of crystalline boehmite AlOOH was fabricated using AlCl3.6H(2)O as the alumina precursor in the presence of N-cetyl-N,N,N-trimethylammonium bromide surfactant, and tubular gamma-Al2O3 was obtained by calcination of boehmite AlOOH at 520 degreesC.
