Hydrothermally grown porous FeVO4 nanorods and their integration as active material in gas-sensing devices
Original language description
Controllable fabrication of highly porous iron vanadate (FeVO4) thick film consisting of disordered nanorods suitable for gas penetration and permeation was achieved by hydrothermal synthesis of fervanite-like FeVO4 center dot 1.1H2O. The subsequent dehydration to FeVO4 was investigated by Fe-57 Mossbauer spectroscopy (DQS), DTA, magnetic susceptibility (c) and electron microscopy (REM/TEM). Their integration in gas sensing devices as porous layer via polymer-blended (PVDF) doctor-blading approach was successfully demonstrated followed by investigations of their electric properties and oxygen sensing capability. The probed I-U behaviour and UV-Vis measurements confirmed the semiconducting nature of triclinic FeVO4 (E-g = 2.72 eV) and exhibited an activation energy for electric conduction of 0.46 eV. The best sensitivity of 0.29 +/- 0.01 (m = -3.4 +/- 0.1) could be obtained at an optimal working temperature of 250 degrees C.
