Iron oxide and various metal oxide nanotubes engineered by one-pot double galvanic replacement based on reduction potential hierarchy of metal templates and ion precursors.


ABSTRACT: A one-pot double galvanic approach was explored for the rational synthesis of metal oxide nanotubes, predictable based on the reduction potential hierarchy of templates and ion precursors (e.g., Ag nanowire substrate is oxidized by MnO4 - ions and it is consecutively reduced by Fe2+ ions to form an Fe2O3 nanotube). This method generated a variety of metal oxide nanotubes via a redox potential landscape.

A one-pot double galvanic approach was explored for the rational synthesis of metal oxide nanotubes, predictable based on the reduction potential hierarchy of templates and ion precursors (<i>e.g.</i>, Ag nanowire substrate is oxidized by MnO<sub>4</sub> <sup>-</sup> ions and it is consecutively reduced by Fe<sup>2+</sup> ions to form an Fe<sub>2</sub>O<sub>3</sub> nanotube). This method generated a variety of metal oxide nanotubes <i>via</i> a redox potential landscape. ...[more]
