“…The properties of titanium dioxide film may depend on the kinds of electrolytic solution for the oxidation of titanium plate. We used mainly nitric acid [12,13] because the titanium dioxide from this solution showed a higher photocurrent response than those from sulfuric acid, chloric acid, and phosphoric acid.…”

“…In the case of using the TiO 2 electrode (geometric surface area: 25 cm 2 ) prepared from anodic oxidation of Ti in HNO 3 solution and then heat-treatment at 500°C, the intermediates due to oxidation of VA were clearly detected [12]. In this case, the electrolytic solution (volume: 420 ml) of two electrodes was aqueous 10 mM NaCl solution containing 50 μM VA.…”

“…There are a lot of reports of photoelectrodes and photocatalysis concerning water decomposition and environmental purification [1][2][3][4][5][6][7][8][9]. We have been investigating photoelectrochemical processes on semiconductor electrodes [10][11][12][13][14][15][16][17]. In the case of oxidation and reduction of chemical species in the solution, using a semiconductor electrode is preferable because reaction control may be possible by an applied voltage.…”

For the purpose of conversion of solar energy to chemical energy and water purification, we have investigated the photoelectrochemical process on semiconductor electrodes. As the electrodes, we focused on TiO2, ZnO, α-Fe2O3, and Cu2O. The TiO2 electrode was prepared from the anodic oxidation of Ti. The sintered ZnO and the electrochemically deposited film were used as ZnO electrodes. The α-Fe2O3 and Cu2O electrodes were prepared from the deposited film by pulse electrolysis. The flat-band potential and photocurrent were checked for these semiconductor electrodes in the solution. The HPLC analysis was carried out for intermediates generated due to the photoelectrochemical reaction of organic materials. The performance of the apparatus for water purification was tested.
