Fig. 4: Reaction pathways and mechanisms of H2O2 photosynthesis.
From: Dual donor-acceptor covalent organic frameworks for hydrogen peroxide photosynthesis
a Amount of H2O2 generated on TaptBtt in CH3OH (10% V/V, as the hole trapping agent), H2O2 produced in AR and KBrO3 (0.01 M). Conditions: water (50 mL), catalyst (15 mg), 300 W Xe lamp, λ > 420 nm. b Kouteckly-Levich plots obtained by RDE tests versus Ag/AgCl. c ·O2− yields of TpaBtt, TapbBtt and TaptBtt detected by NBT method under light conditions. d 18O2 isotope experiment for TaptBtt. e In-situ DRIFT spectra of TaptBtt. f Mechanism of TaptBtt for photocatalytic H2O2 formation. The white, gray, blue, yellow and red spheres refer to hydrogen, carbon, nitrogen sulfur and oxygen, respectively.
