Photocatalytic formic acid decomposition is done by electrochemical and photocatalytic methods andis studied in a single cabinet  photoelectrochemical cellwhich is included TiO₂ Nano crystalline electrodes. Due to P25 inactivitydegasa was prepared in plated glass with tin oxide.Applying +1 V ( SCE ) in the TiO₂electrode leading to substantially increase in the rate of formic acid decomposition speed in anaerobic and weather broadcast conditionscomparetoopen circuit electrode.When solution was distributed with O₂positive bias will not result in a significant increase in speed. The second cathode cabin added to the cell coincidence withphotocatalytic oxidation of formic acid to revival of copper ion from solution.DecomposedFormic acid in photoanod and copper, in copper mesh cathode was revived with high efficiency.
