Abstract |
For facile synthesis of hexagonal shaped γ-Al(OH)3, we adopted a procedure to synthesize colloidal gibbsite nanosheets from a single aluminum alkoxide (Al[OCH(CH3)C2H5]3, aluminum sec-butoxide) as precursor. The introduction of a preheating step accelerated the precursor’s hydrolysis/peptization and considerably shortened the overall reaction time. We have synthesized hexagonal shaped γ-Al(OH)3 nanosheets which have near 700nm of size and 35nm of thickness by seed generation reaction and one crystal growth. The Langmuir-Blodgett (LB) synthesis is one of highly reproducible and controllable methods of organizing anisotropic particles with a preferred orientation over a relatively large surface area. In this way, hexagonal shaped aluminum hydroxide (γ-Al(OH)3, gibbsite) nanosheets were assembled at solid substrate into a compact and preferred orientation with regular layers extending near the centimeter scale.
