Figure 13. Electrolysis of an aqueous 0.1 M LiClO₄ solution with two platinum electrodes (driving electrodes). A polypyrrole-coated FTO glass disc (as BPE) was placed between the electrodes. a) At the beginning of the electrolysis. b) After about one minute. c) Shortly after interrupting the electrolysis. d) Electrolysis for one minute after reversing the polarity. e) The current supply is interrupted again (about 15 seconds). f) The electrolysis is continued for one minute after the polarity has been reversed for the last time.
