(a) Comparison of decolorization of MB dye solution by different systems. Common conditions: 25 mL of 5 mg L–1 MB in 0.1 M Na2SO4 at pH 4, under constant stirring. The independent conditions were as follows: Ti–O–CuNT electrode, [PMS] = 0.780 mM, potential of 0.5 V vs Ag/AgCl, 10 W UV LED irradiation at 365 nm; (b) % of decolorization in 30 min of treatment by the different evaluated systems. (c) Comparison of decolorization of MB dye solution by PEC (■) and PEC/aPMS (●) with Ti–O–CuNT (red) and TNT (black) electrodes.
