N-type semiconductor tungsten oxide is an interesting photocatalytic material because it has a good band gap (2·6 eV). This experiment using the surfactants citric acid and tannic acid acts on an aqueous solution of tungsten oxide, helps in the formation of different crystal growth surfaces and thus achieves a mixed solution of tungsten oxide to obtain a different optical, surface morphology and its two kinds of citric acid and tannic acid mixed ratios of the tungsten oxide specimen test the efficiency of solar hydrogen production. The efficiency test results in maximum efficiency, reaching 0·85% WO3 (citric acid:tannic acid = 1:3) of the solar hydrogen production efficiency. The efficiency will possibly be up to 3% after optimization.
