Fig. 4

a Photograph of the three-phase flow cell reactor system and (b) schematic diagram of the three-phase flow cell reactor. Rflow cell = 1.9 ± 0.1 Ω. c The V-t curve of Se2‒Pt NPs tested in flow cell reactor with current density of 250 mA cm−2 in 0.1 M HClO4. Insets are the photograph of cathode electrolyte and the working conditions, respectively. (mass loading: 0.2 mgPt cm−2; O2 flow rate: 10 mL min−1; temperature: 25 °C) (d) H2O2 production and corresponding Faradaic efficiency of H2O2 of Se2‒Pt NPs tested in the flow cell reactor with the increase of time. The UV-vis spectra and photographs of (e) methylene blue (MB), (f) malachite green (MG), and (g) rhodamine B (RB) solutions before and after degradation.
