Electrochemical water oxidation by Cu-based cluster was investigated. Linear sweep voltammetry revealed the lower overpotential of cluster catalysts than Cu, Cu2O and CuO particle coated electrode. Current-time depencdence for 24 hours revealed oxygen evolution with faraday efficiency of about 100 %. The actual catalyst was estimated to be fabricated during electrochemical measurements.
