The cleaning/activation of Pd electrodes can be carried out using cyclic voltammetry. Just run a few cycles in acid or alkaline medium using your Pd electrode. Record in the potential ranges where the hydrogen UPD regions and Pd surface oxide formation occurs. More the number of cycles the electrode get activate to a larger extent.

A palladium electrode is cleaned in cold concentrated nitric acid. palladium electrode is always carefully polished.
