Fig. 5: Photocatalytic mechanism of PM-CDs-30.
From: A metal-free photocatalyst for highly efficient hydrogen peroxide photoproduction in real seawater
TPV curves of a PM-CDs-0, b PM-CDs-30 before and after adding NaCl. c The photocatalytic H2O2 production rates upon the addition of different sacrificial agents. d EPR diagrams of PM-CDs-30 under darkness and light. e The production rate of H2O2 by photocatalytic reaction in different gas environments. f TPV curves of PM-CDs-30 under different conditions. g H2O2 production rate varies with ion concentration in different salt solutions. *P < 0.10; **P < 0.05; ***P < 0.01. The vertical error bars indicate the maximum and minimum values obtained; the dot represents the average value.
