*2.2. Photochemistry Experiment*

All experiments were conducted in a multichannel photocatalytic reaction system (PCX50C, Beijing Perfect Light Science and Technology Co., Ltd., Beijing, China). The system was operated at an average light intensity of 10.0 mW cm<sup>−</sup><sup>2</sup> with 5 W LED white lamps (365 nm). During the 6 h photochemical experiments, 50 mL of the reaction solutions was magnetically stirred at 300 rpm in quartz tubes that were maintained at constant temperature (22 ± 2 ◦C) with the circulating water bath of the reactor.
