Abstract
A nickel cathode has a nickel oxide layer on its surfaces. A plurality of spaced apart grooves are in the nickel oxide layer and extend into the nickel. The cathode can be utilized in a water photolysis apparatus which also includes an N type photocatalytic semiconductor anode. Both the cathode and anode are in an aqueous basic electrolyte solution. The anode and cathode are electrically biased by a solar cell. The biasing potential of the solar cell raises the voltage potential of the cathode and lowers the Fermi level of the anode.
