Study of electrochemical based gas sensors for fluorine ...

Abstract Electrochemical cells are fabricated with sodium as the anode and mixture of V 2 O 5 + graphite powder (50:50) as cathode. Dry and plasticized polyethylene oxide (PEO)-based electrolytes were employed in the above cells. Fluorine and chlorine gases were allowed through the cathode surface, the resulting galvanic effects were monitored. The working of the sensor and its limitations …

Copper oxide-polyaniline nanofiber modified fluorine doped ...

01/08/2018· In this study, copper oxide-polyaniline nanofiber modified fluorine doped tin oxide (CuO/PANI-NF/FTO) electrode is introduced as a non-enzymatic glucose sensor. PANI-NFs were polymerized by a chemical method and through a cellulose ester membrane. These fibers were dip coated on FTO and then CuO particles were deposited on PANI-NFs by the electrodeposition method …
