Abstract

Vanadium oxide nanorods were prepared by a hydrothermal route and then tested as a transducer for a resistive‐type gas sensor. The importance of control of pH and pressure during the synthesis of 1D crystals of vanadium oxide was demonstrated for the V~2~O~5~/ethanol mixture, which served as a precursor. As a gas sensor element, the nanorods demonstrated a stable response to triethylamine and weak sensor response to carbon monoxide with a short response time (as low as 32 s).
