The generated H2O2 concentration Ctitration was evaluated using standard potassium permanganate (0.1 N KMnO4 solution, Sigma-Aldrich) titration process, according to the following equation: 5H2O2 þ 2KMnO4 þ 3H2SO4 ! 5O2 þ 2MnSO4 þ K2SO4 þ 8H2O ð6Þ Theoretical concentration ...
[d] With the addition of AgNO3 as electron trapper, other conditions as [b]. The concentration of produced H2O2 was determined by KMnO4 titration20. in Table S1, which clearly demonstrates that the molar ratio of C, N, S and Cd elements is 1: 0.98: 0.91: aa0nl.s5do5.FdTTehnIeRo...
namely OOH*, with a suitable binding energy that could facilitate its single-electron reduction to H2O2, but suppress it from being further reduced or dissociated to O* and OH* that will eventually form H2O7,22. Thus far, porphyrins containing 3d transition metals...
