Scope of PEC oxidative chlorination reactions on α-Fe₂O₃ photoanodes.

^atypical reaction conditions applied in this work: 0.1 M NaCl, 0.1 mmol substrate in 10 mL of CH₃CN solution with 50% H₂O (v/v = 1 : 1), PEC reactions were carried out for 2 h under AM 1.5G irradiation at 1.0 V vs. Ag/AgCl with a non-conditioned air atmosphere and pH adjustments.
