Photoresponse of Visible Light Active CM-n-TiO₂, HM-n-TiO₂, CM-n-Fe₂O₃, and CM-p-WO₃ towards Water Splitting Reaction

Figure 20

Photocurrent density (𝑗_𝑝, mAcm⁻²) versus measured potential (𝐸_meas, V/SCE) for oven-made n-Fe₂O₃ (sample A) and flame-made CM-n-Fe₂O₃ (sample B) under light intensity of 100 mW cm⁻². Both samples were prepared at the same optimum conditions of 850°C for 15 minutes. 5.0 M KOH was used as an electrolyte solution [23].
