Abstract. Current creation caused by water decomposition Н2О → ОН+Н has been
investigated for the case of an Yb-Si electrode pair after the preliminary covering of Si
electrodes with transition metal (Ni, Ti, Cr) films, as well as exposing them to laser
radiation. It has been shown that laser radiation, as a rule, increases the efficiency of
current creation owing to the improvement of electrode catalytic properties as to water
decomposition. We observed also some change in the electron work function for these
electrodes.
Keywords: water decomposition, current creation, electron work function.
