Metal plated carbon electrodes

Ninja - 5-12-2014 at 19:45


In place of using ordinary metal electrodes, i carry out a thermolysis of succrose on a hard and electrically insulating material such as glas and deposit (usually a foam like) layer of metal by electrolysis on it.
Can i use such an electrode like a pure metal electrode with a much greater surface area? Has this kind of plated carbon electrode have some special properties?
May is use activated carbon as base for another metal plated electrode?

What do you think about this matter?
I hope for many good answers :-) ...

Thanks, Ninja

I've seen plated electrodes in voltametry, coulometry, etc. Sometimes they are preferred, but I don't know enough about the specifics of electrodes to give you more information.

Certainly a plated electrode such as you suggest will have different current flow, but I am not sure if that will be of any experimental significance.

The name of this class of carbon modifications is "pyrolytic carbon".
"Copper electrodeposition on pyrolytic graphite electrodes: Effect of the copper salt on the electrodeposition process" is a paper about something i described.
Has someone more information about this kind of electrodes?
