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

摘要

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 MnO _(4) ~(?) ions and it is consecutively reduced by Fe ~(2+) ions to form an Fe _(2) O _(3) nanotube). This method generated a variety of metal oxide nanotubes via a redox potential landscape.
