Electrochemical Photolysis of Water at a Semiconductor Electrode

  title={Electrochemical Photolysis of Water at a Semiconductor Electrode},
  author={A. Fujishima and K. Honda},
ALTHOUGH the possibility of water photolysis has been investigated by many workers, a useful method has only now been developed. Because water is transparent to visible light it cannot be decomposed directly, but only by radiation with wavelengths shorter than 190 nm (ref. 1).
