Surface Potential of Polycrystalline Hematite in Aqueous Medium
Figure 3
Electrode potential of nonporous polycrystalline hematite electrode (equilibration time: ~10 min) as a function of pH of the solution in the presence of NaClO4 ( mol dm−3). Titration of acidic solution with NaOH (♦), and back titration of basic solution with HClO4 (▲). Temperature: 25.0°C.
