| Fig. 5 Comparison in polarization curves of (A) Cr/N/C-950 and (B) Fe/N/C-950 initially and after the accelerated degradation tests for 20000 cycles. (C) Top: reaction between ROS and ABTS; Bottom: photographs showing the color change of the solution after Fenton reaction. (D) UV-Vis absorption spectra of 0.1 mol·L-1 HClO4 solutions included only ABTS; Cr/N/C-950 and ABTS; H2O2 and ABTS; Fe/N/C-950 and ABTS; Cr/N/C-950, H2O2 and ABTS; Fe/N/C-950, H2O2 and ABTS after 7-min reaction. Inset presents the absorbance change at 417 nm after subtraction of the value of H2O2 + ABTS treated solution. Blue: Fe/N/C+H2O2+ABTS; Cyan: Cr/N/C+H2O2+ABTS[ |
