Abstract

We report the direct growth of highly single crystalline rhenium trioxide (ReO₃) nanorods on a tungsten (W) microwire electrode via the physical vapor transport process without any catalyst. In our growth mode, ReO₃ nanocubes were initially formed on the surface of a tungsten (W) microwire electrode and further they were anisotropically grown along the [001] crystallographic direction. Furthermore, we performed the fundamental electrochemical experiments so that from cyclic voltammetric measurements, ReO₃ nanorods on a W microwire exhibit a good capacitance and Nernstian behavior for a Fe(CN)₆³⁻/Fe(CN)₆⁴⁻ redox couple in 1 M KNO₃ aqueous solution, indicating a promising electrode material for electrochemical applications.
