The boehmite (Al 2 O 3 ·H 2 O) hierarchical nanostructure with spindle‐like morphology has been successfully synthesized via ionic liquid‐assisted hydrothermal synthetic method under mild condition using an ionic liquid 1‐butyl‐3‐dimethylimidazolium bromide ([Bmim][Br]) as a template. The proposed formation mechanism has been investigated and the hydrogen bond‐ co‐π–π stack mechanism is used to be responsible for the present formation of the precursor hierarchical nanostructure. The γ‐Al 2 O 3 hierarchical nanostructure was obtained by calcining the as‐synthesized precursor at 500 °C for 2 h, preserving the same morphology. (© 2010 WILEY‐VCH Verlag GmbH & Co.
