rogeryermaw Posted August 3, 2014 Share Posted August 3, 2014 File Name: PbO2 anodeFile Submitter: rogeryermawFile Submitted: 03 Aug 2014File Category: Chemistry & Experiments preparation of lead dioxide for electrolytic deposition on an inert substrate. many methods are discussed for the prearation of lead dioxide electrodes but most require materials that are out of reach or too expensive for the home experimenter. my research indicates that lead dioxide may be deposited electrolytically onto titanium electrodes but not directly. there must be an intermediate layer since PbO2 will passivate titanium. exotic metals have been used in industry but they are ridiculous in cost. the cheaper solution is to first prepare or obtain manganese dioxide coated titanium electrodes onto which the PbO2 coating may be electrolytically deposited from solution of acetic acid. correct me if i'm wrong, but i believe that the electrode must be used as a cathode to deposit the lead from solution. the prepared electrode may then be used as an anode in electrolysis projects after the desired number of layers have been achieved.

WSM Posted August 4, 2014 Share Posted August 4, 2014 What sort of file is this? I can't seem to open it. WSM Link to comment Share on other sites More sharing options...
mabuse00 Posted August 4, 2014 Share Posted August 4, 2014 Seem like a normal pdf?I use the PDF-XChange Viewer and i opens without issues. Thank you Roger. Link to comment Share on other sites More sharing options...
WSM Posted August 4, 2014 Share Posted August 4, 2014 (edited) Okay, now it worked. Like mabuse00 said, it came through as a .pdf file. I don't know what happened the last time; it just wouldn't show up. Thanks, Roger. It looks like it'll make for interesting reading (I'll report later).

schroedinger Posted August 12, 2014 Share Posted August 12, 2014 No, a cathode is the electrode where the reduction part is happening. But since we want the oxide we have to plate on the anode where the oxidation is happening Link to comment Share on other sites More sharing options...
