a Time-dependent H2O2 production curves of all the B[f]QCOFs under visible-light irradiation over 2 h. b AQYs of B[f]QCOF-1 at different selected wavelengths (450, 475, 520, 550, 600, 650 nm). Error bars indicate the error in the measurement. c The photocatalytic performances of all the B[f]QCOFs in different kinds of water under Xenon lamp irradiation. d The photocatalytic performance of the B[f]QCOFs in comparison with reported COF-based photocatalysts. e The formation (Kf) and decomposition (Kd) rate constants of H2O2 for B[f]QCOF-1. f Recycling experiments involving the photocatalytic production of H2O2 with B[f]QCOF-1 as the photocatalyst. g The control experiments showing the H2O2 production performance of B[f]QCOF-1 under various conditions. BA Benzyl alcohol, TEMPOL 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl.
