Notes:
In this study, an anodized TiO2 electrode (ATE) on a titanium foil was prepared and used asa photoanode in an enzymatic photoelectrochemical system to split water into oxygen and hydrogen.The effect of applied voltage when anodized, thickness of foil, electrolytes, annealing temperature,and species of cathode was investigated. The optimum conditions were obtained such as 0.25 mm foilthickness, 20V of applied voltage in 0.5 vol% of hydrofluoric acid, and 650 oC of annealingtemperature. The samples with higher activities had similar X-ray diffraction (XRD) patterns, clearlyindicating that the samples showing the highest evolution rate were composed of both anatase andrutile, while those showing a lower evolution rate were made of either anatase or rutile. Increasing theintensity of the irradiated light caused a remarkable enhancement in the rate of hydrogen productionup to 153 μmol/(hr×cm2) under light intensity of 146 mW/cm2
