(a) Effects of different oxygen flow rates on the performance of reactions with 8 mL ultra-pure water, 2 mL cyclohexane, 50 mg 0.3C3N4/WO3, and irradiation for 6 h, (b) effects of different volume fractions of water in water/acetonitrile mixtures on the performance of reactions with 8 mL water/acetonitrile mixed liquor, 2 mL cyclohexane, O2 at 6 mL min−1, 50 mg 0.3C3N4/WO3, and irradiation for 6 h.
