a
Reaction conditions: aqueous glucose (1 mmol·l−1, 30 mL), catalyst (20 mg), reaction for 3 h, and light intensity (1.5 W·cm−2). (Note: GAA, glucaric acid; GOA, gluconic acid; FA, formic acid).
b
Without light irradiation. (Note: GAA, glucaric acid; GOA, gluconic acid; FA, formic acid; TOA, total organic acid).
