Fig. 2: Photocatalytic production of H₂O₂.

a Time-dependent production rate of H₂O₂ on TT–CTP and TTH–CTP in pure water. b H₂O₂ generation rates of photocatalytic half-reaction of TT–CTP and TTH–CTP with and without benzyl alcohol as a hole sacrificial agent. c UV–Vis spectra and AQY of H₂O₂ generation for TT–CTP and TTH–CTP. d H₂O₂ generation rates and AQY of different photocatalysts. The red star represents TTH–CTP in this work (with benzyl alcohol, see panel b) and the orange, green, sky-blue, and blue circles correspond to other previously reported photocatalysts. e H₂O₂ generation rates of photocatalytic half-reaction of TT–CTP and TTH–CTP under different pH values. f H₂O₂ generation rates of photocatalytic half-reaction of TTH–CTP under different cycles.
