• thin film of about 10 μm thickness with a roughness factor of about 1000. For Figure 2 and Figure 5–7, T/SP TiO2 was used and, in order to bring the other side of a Pt cathode in contact with air, a membrane electrode assembly (MEA) (1 cm × 1 cm) purchased from FC Development Co., Ltd., Japan was used

• with a coated area of 1 cm × 1 cm. For this procedure, adhesive tape (thickness about 70 μm) was used as a spacer to adjust the TiO2 film thickness to around 10 μm after calcination. The TiO2 paste film on FTO was dried at room temperature, and then calcined at 450 °C for 30 min to give a nanoporous
