Recently, we have found that Cu<SUB>2</SUB>O powder suspended in distilled water by stirring decompose water catalytically into H<SUB>2</SUB> and O<SUB>2</SUB> under visible light irradiation. To our surprise, the experiment revealed that the catalytic decomposion of water by Cu<SUB>2</SUB>O is due to the mechanical energy produced in to stirring and the reaction under stirring was enhanced by the irradiation of visible light having photon energies more than the band gap energy of Cu<SUB>2</SUB>O(2 eV). The reaction is regarded as "mechano-catalytic overall splitting"; and is distinct from conventional photocatalytic water decomposition.
