TiO2: Cr nanopowders for hydrogen sensing.
In: Procedia Engineering, 25 (0)
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
The aim of this research was to use nanocrystalline TiO2 and TiO2: Cr (0.1–10 at. % Cr) obtained by Flame Spray Synthesis, FSS, for hydrogen sensing. Morphological properties of nanopowders were investigated by Brunauer–Emmett–Teller, BET, adsorption isotherms, X-ray Diffraction, XRD, Scanning Electron Microscopy, SEM, and Transmission Electron Microscopy, TEM. Nanosensors were prepared in a form of circular tablets by pressing the nanopowder at the pressure of 25 MPa and heating up to 400oC. Dynamic changes in the electrical resistance ΔR/Ro upon hydrogen exposure were detected over low-to- medium concentration range of 50-3000 ppm at 200-400oC. The influence of particle size and Cr content on the sensor response was studied.
