1. A method for electrochemical hydrogen production from water oxidation and proton reduction by covalently attaching a ruthenium complex onto a conducting material, comprising fluorine-doping a carbon cloth to provide a fluorinated carbon cloth (FCC) and using the FCC as at least one of an anode and a cathode in an electrochemical cell.
