This
paper reports the nucleation and growth of 2D δ-MnO<sub>2</sub> nanosheets from a simple wet chemical reaction at low temperature.
The reaction between aqueous KMnO<sub>4</sub> and pure ethyl acetate
constitutes a new a biphasic platform for product evolution. Then
the synthesized δ-MnO<sub>2</sub> nanosheets undergo shape transformation
to 1D α-MnO<sub>2</sub> nanowires in the same pot via a dissolution–recrystallization
mechanism. The detailed growth mechanism of nanosheet formation and
the morphology transformation are described in this paper. Moreover,
this low temperature technique can be used to produce ultralong α-MnO<sub>2</sub> nanowires in industrial amounts which are difficult to synthesize
by conventional high temperature methods. In this method, we have
prepared 25.00 g of α-MnO<sub>2</sub> nanowires in our nanomaterial
laboratory from 18 batches. Lastly, solvent-free catalytic activity
of α-MnO<sub>2</sub> nanowires is investigated for the hydrolysis
of benzonitrile to benzamide in one step.
