Abstract

A method is provided for conducting electrolysis at or below 1.23 V. The method comprises filling an electrolysis reactor having an aluminum anode and a copper cathode with a sufficient amount of solution such that at least a portion of the anode and the cathode are immersed in the solution; the solution comprising water, an electrolyte and a catalyst; and applying a voltage across the reactor of less than or equal to 1.23 V. The solution is comprised of water, aluminum sulfate and an ammonium salt. The method allows for total gas to be produced at a rate in excess of the theoretical maximum 1.06 l/min at a current of 93 amps.
