These compounds were used as photosensitizers in three component system containing methyl viologen (MV2+) and Na2EDTA. Different behaviors of the hydrazones were observed as photosensitizers depending on their oxidation potential values and their stability in irradiation solution. Rate constants of methylviologen reduction by the photochemical active hydrazones were recoded and hydrogen was photoproduced using TiO2 as catalyst
