Abstract:

A simple steam-assisted solid phase synthesis method was developed for synthesis of boehmite nanowires in the presence of TEAOH surfactant. The boehmite nanowires had uniform diameters (12–16nm) and length up to 1–2 m. The morphology of the nanostructured wires was well preserved after being converted to pure -Al2O3 by thermal treatment at 600 °C for 5 h. The nanowires of Al2O3 exhibited excellent thermal stability by retarding the phase transformation and maintaining the wires-like nanostructure after being aged up to 1300 °C by preventing sintering between particles at high temperatures. The surface areas of Al2O3 nanowires could be maintained as high as 68 m2/g at 1300 °C while the surface areas of Al2O3 micropowder shrank to 0.89 m2/g after same thermal treatment. Both in-situ XRD and 27Al NMR results indicated that the crystal structure of -Al2O3 nanowires was not transformed to α-Al2O3 at 1300 °C whereas micropowder Al2O3 was fully converted to α-Al2O3 at 1100 °C.
