摘要：

In the present study, the electrophoretic deposition technique was successfully employed to deposit Pt/C particles on hydrophobic Polytetrafluoroethylene membranes in non-aqueous media for electrochemical gas sensing applications. Optical microscopy studies showed that uniform crack-free layers were obtained at potential interval of 30-50 V on the non-conductive Polytetrafluoroethylene membrane in appropriate durations. The Pt/C deposit formed at 30 V for 10 min was then electrochemically examined as the working electrode of an electrochemical carbon monoxide gas sensing cell where linear scan voltammetry of the fabricated Pt/C electrode revealed clear and reproducible response to CO gas in H2SO4 solution.
