Fig. 2: Investigation into the mechanism of H2O2 generation by FCPs/CEC.
From: FeIII-driven self-cycled Fenton via contact-electro-catalysis for water purification
Time course of the H2O2 generation by FCP/CEC with different FCPs (a). Comparison of the H2O2 generation rate with previous CEC and piezo-catalysis (b). Time course of the H2O2 generation measured under different reaction conditions (c). Relative quantitative analysis of *OH in FCP/CEC (d). Free energy profiles of the indirect 2e– WOR process in FCP/CEC were compared with (FCP-IEF) and without IEF (FCP-Normal) (e). Schemic of H2O2 generation in FCPs/CEC (f). Experimental conditions: [FCPs]0 = 0.1 g·L–1, T = 25 ± 2 °C.
