Figure 6. Time courses of overall water splitting into H2 (☐) and O2 (○) by 3PVs.

Figure 6

Overall water splitting were demonstrated by (a) 3PVs fixed in 0.5 M KOH aqueous solution as an electrolyte, (b) 3PVs fixed above the electrolyte, and (c) 3PVs with MCPET fixed above the electrolyte under irradiation of solar simulator (AM1.5G). As the electrocatalysts, combination of NiFeOx (anode) and Pt/Ni (cathode) was used with geometric surface area of approximately 0.34 cm2 and 0.45 cm2 for 3PVs (a,b) and 3PVs with MCPET in air (c), respectively. The reactions were measured in a Pyrex top-irradiation flow cell at room temperature.
