Efficient Proton Transfer and Charge Separation within Covalent Organic Frameworks via Hydrogen-Bonding Network to Boost H2O2 Photosynthesis

“…The results indicated that COF@H 3 PO 4 possesses a much higher photogenerated carrier separation efficiency compared to the COF. − In addition, the photogenerated carrier transfer rate was further probed by using electrochemical impedance spectroscopy (EIS), where samples with smaller radius arcs have lower charge transfer resistance. As shown in Figure e, EIS results confirmed that the electronic conductivity of COF@H 3 PO 4 was superior to that of COF, since COF@H 3 PO 4 has a much smaller EIS Nyquist curve radius. , The time resolution photoluminescence (TRPL) spectrum was also measured to reveal the charge separation dynamics processes of the catalysts (Figure f). The mean radiative lifetimes of charge carriers were determined by fitting double-exponential functions to the corresponding TRPL peak, and the results are provided in Table S1.…”
