| Summary: | 碩士 === 國立成功大學 === 化學工程學系 === 105 === In this work, anatase titanium dioxide (TiO2) structures have been deposited on fluorine-doped tin oxide (FTO) by hydrothermal method for the application to photoelectrochemical water splitting. The performance of anatase TiO2 photoanode was optimized in terms of deposition conditions, including annealing temperature of seed layer, period of hydrothermal growth, concentration of titanium(IV) n-butoxide, temperature of hydrothermal growth and saturated sodium chloride solution. The optimized anatase TiO2 photoanode produces a photocurrent density of 0.279 mA/cm2 at a potential of 1.23 V versus RHE under illumination of AM 1.5G (100 mWcm-2). The photocurrent density of the anatase TiO2 photoanode over a period of 600s is reduced only 8%.
