Electrophoretic deposition

  • The photoelectrode with TiO2 powders is prepared using an electrophoretic deposition method.
  • Typically, 5 mg of iodine and 10 mg of TiO2 powder are dispersed in 25 mL of acetone. The electrophoretic deposition process is conducted between two parallel ITO electrodes with a distance of 1 cm under 15 V of bias for 5 min.
  • The electrode is then heated to 400 °C for 30 min under a nitrogen atmosphere.
