RFQ: I am experimenting with plating for neurological studies and am having trouble finding source of Platinum black on the web. Can anyone help?

Q. Update: I have found suppliers but I still need information on how much PtBlk/liter to use when I plate a Pt electrode. I have read several papers, (Mareese, Feltham/Sriro, Mills, Desai, etc.), they all talk about the plating solution, (typically Cloroplatic acid and a lead compound), but none indicate how much Platinum Black they used.

A. It depends on what you want to do? To plate platinum black on platinum? In that case you can use next solution and process (According to: G.Buchner:Metallfaerbung,Berlin 1922.): 300 mll water, 10 gm platinum chloride/0,08 gm lead acetate [affil. link to info/product on Amazon], 4-6 V, current density must be so strong that many gas bubbles forms, after 3-4 minutes poles must be reversed(+=-,-=+) and after 10 minutes black platinum must be formed. Hope it helps and good luck!

thumbs up signThanks for your response. One of my pitfalls was thinking that platinum black needed to be added to the bath rather than the Pt being reduced from the chloroplatic acid.
