Nanoporous Nb2O5 hydrogen gas sensor
This work presents the development of gas sensors based on nanoporous niobium oxide (Nb2O5) films for hydrogen gas sensing. Nanoporous Nb2O5 films were successfully synthesized by the anodization of niobium foil in fluoride-organic solvent containing a small percentage of water at 50 °C. These condi...
