Hello everyone,
Recently I am working on formation of nanowires on HOPG by electrodeposition. I started with Pd by using PdCl2 in HCl, and it worked. Pd NWs are formed on HOPG. However, my goal is Ir electrodeposition, not Pd. I tried to change the Pd salt with Ir salt, but it did not work. I have tried to follow other group recipes for Ir electrodeposition, but it ended with Ir layer or Ir nanoparticles. Does anyone have an experience with Ir electrodeposition on HOPG? or Ir nanowires formation by electrodeposition?
May you share to me, I will appreciate it. Thank you.
Dear Anafi Nuraini , may be the following paper could help you. In this case the authors used a nanoporous alumina template to obtain 60:40% platinum-iridium alloy nanowires of about 200nm diameter and controllable length (it will depend on the depth of alumina pores). As seed layer they deposited Ti/Au thin films by sputtering. I know it is not exactly what you was asking for, but may be you can adapt the method to your experiments.

May be another option would be to deposit some seed nanoparticles, say Ti/Au like in this case, or may be replicating the first stage of your Pd deposition, and then shifting to an Ir salt, probably if you obtain some kind of distribution of NP´s on your HOPG, Ir could grown from them up, forming the Nanowires instead of thin layer.
Hope it helps.
