“…/Fe 2+ = 0.77 V, E Cu 2+ /Cu + = 0.15 V, etc. ), [14][15][16][17] which makes the reaction of Co 3+ with HSO 5 À (E ÁSO 5 À =HSO 5 À ¼ 1:10 V) thermodynamically permitted and hence a cycle of Co 2+ -Co 3+ -Co 2+ can be quickly established for continuous PMS activation. Additionally, the leaching content of cobalt ions into the solution is very low during the catalytic reaction by virtue of the stable spinel structure of Co 3 O 4 .…”

“…The applied voltage is critical for the cycling of Fe 3+ /Fe 2+ pairs of the Fe-MOF [30]. The TC degradation efficiency was 58.3% (k = 0.039 min −1 ), 78.2% (k = 0.066 min −1 ) and 98.3% (k = 0.159 min −1 ) at applied voltages of −0.5 V, −1.5 V and −2 V, respectively (Figure 4b).…”

“…Nevertheless, further decreasing the applied voltage to −2.5 V only led to a decreased TC removal efficiency of 83.3% (k = 0.082 min −1 ), possibly due to the occurrence of other side reactions (e.g., hydrogen generation reaction) that decrease the current efficiencies [31].
