Photoelectrochemical Properties of Fe_𝟐O_𝟑 Supported on TiO₂-Based Thin Films Converted from Self-Assembled Hydrogen Titanate Nanotube Powders

Figure 4

I-V characteristic curves for Fe₂O₃ films with various amounts of 0~100 wt% supported on H-TiNT/FTO film, followed by heat treatment at 500°C for 10 min in air. Here, 0 wt% means that there are no Fe₂O₃ particles on H-TiNT/FTO film and 100 wt% means Fe₂O₃ particles covered fully on the surface of the film.
