I have a platinum electrode so is it possible to deposit Pt on ITO (Or other conducting substrate) without using any Platinum electrolyte? I don't have any Pt salt electrolyte so please give method to deposit by just using Pt electrode.
I am afraid that this is not quite possible. You can try to dissolve Pt into an electrolyte with sufficient HCl, so you will form PtCl6, which will then be dissociated at the ITO electrode. But first you will generate a lot of H2 at the ITO electrode before there is sufficient dissolved PtCl6 in the electrolyte.

I think it may actually be possible to easily put your Pt wire in good use. You can try performing the "cathodic corrosion" of your Pt wire, which would theoretically produce Pt nanoparticles below 10nm in size. Then, you could try depositing these nanoparticles on whatever substrate you want.
Quite lots of studies have been published on this topic. You can start with this open-access article:
Angew. Chem. Int. Ed. 2011, 50, 6346 –635, "Cathodic Corrosion: A Quick, Clean, and Versatile Method for the Synthesis of Metallic Nanoparticles"
http://onlinelibrary.wiley.com/doi/10.1002/anie.201100471/abstract
Btw, I would also advice to make sure about the purity of your Pt wire...if you want to form nanoparticules composed of Pt only.
Have fun reading and experimenting !

Hi Vinay,
I don't think it is good idea to perform cathodic /anodic corrosion or dissolution of Pt wire and after that to deposit on conducting substrate. I believe it is quite impossible. Compare to Pt salt, pure Pt is much more expensive. So, try to get the Pt salt and then perform your experiment.
