Thiophene‐Containing Covalent Organic Frameworks for Overall Photocatalytic H2O2 Synthesis in Water and Seawater

“…TD-COF and TT-COF were n-type semiconductors, as indicated by the positive slopes of the Mott-Schottky plots at the isoelectric point in Figures S9 and S10. [23] The flat band potentials of TD-COF and TT-COF were determined to be À 0.65 V and À 0.62 V (vs. Ag/AgCl). Combining the optical band gaps with the Mott-Schottky plots, the conduction bands (CB) of TD-COF and TT-COF were calculated to be À 0.45 V and À 0.42 V (vs. NHE); the valence bands (VB) of TD-COF and TT-COF were estimated to be 2.05 V and 2.06 V (vs. NHE), as illustrated in the band-structure diagrams in Figure 3b.…”

The synergy between a benzoselenadiazole covalent organic framework and TEMPO for selective photocatalytic aerobic oxidation of organic sulfides

“…15 However, the rapid recombination of photogenerated charge carriers and the low utilization of charge carriers in selective oxidations hinders the efficacy of O 2 activation. [16][17][18] The effective generation of reactive oxygen species (ROS) over COFs is imperative to improve the photogenerated charge separation and transport. [19][20][21] To this end, introducing appropriate photoactive building blocks should be of interest to synthesize COFs with improved separation and transport of photogenerated charges.…”

Metal–organic frameworks and covalent organic frameworks as photocatalysts for H2O2 production from oxygen and water

“…80 Besides the post-treatment strategy, they also can be obtained by facile multicomponent reactions (one-pot method). [82][83][84] A recent work in which quinoline-4-carboxylic acid-decorated COFs were synthesized via the threecomponent Doebner reaction for photocatalytic H 2 O 2 production was reported by Thomas's group. 70 As shown in Fig.…”
