The ionic liquid l-n-butyl-3-methylimidazolium tetrafluorob-orate has been used to synthesize nanoneedlcs and nanorods of manganese dioxide (MnO,).192 Crystalline silica nanowires were prepared by Deepalc et al.m by a carbothermal procedure. Crystalline SiO, nanowires have also been prepared by a low-temperature iron assisted hydrothermal procedure.1,5... 

During the past few years, a significant effort has been directed towards the synthesis of low-dimensional Mn02 nanostructures with controlled morphologies. For instance, a-, P-, y-, 6-, k-, and E-Mn02 polymorphs were synthesized in the shape of nanorods [141-145], nanowires [144, 146-148], nanofibers [149, 150], nanoneedles [151, 152], and nanotubes [153, 154]. Lately, the attention of a considerable number of chemists and materials scientists has also been oriented towards the self-assembly of 1-D nanostructured manganese dioxides into 2- and 3-D ordered microstructures [144, 155-158].
