What is the function ( or role ) of platinum in electrochemistry in general ? I read a question about platinum in electric potential , and in standard electrode potential ?!
thank you a lot

H2 gas at a pressure of 1 atmosphere bubbled over "black platinum" in a 1 M solution of H^+ is arbitrarily set at zero. Black platinum is platinum with a fine coating of extremely small particles (granules) of Pt. That surface apparently gives better reproducibility than just a pure Pt electrode.
