Mn doping improves in-situ H2O2 generation and activation in electro-Fenton process by Fe/MnCC cathode using high-temperature shock technique
Copyright © 2022 Elsevier Ltd. All rights reserved..
Fe/Mncarbon cloth (CC) was successfully fabricated through high-temperature shock (HTS) technique and used as cathode modification in heterogeneous electro-Fenton (hetero-EF) process for methylisothiazolinone (MIT) degradation. The nanocrystalline on Fe/Mn@CC electrode is doped with Fe and Mn oxides and coated with carbon layer, which could markedly enhance the electrocatalysis with high electro-chemical active area and low resistance. Fe/Mn@CC modified cathode can efficiently in-situ produce and activate H2O2, showing high electrocatalytic activity to MIT degradation. The 95.2% MIT degradation with in 100 min were achieved under the condition of 30 mA current, 0.75 L min-1 aeration intensity and initial pH = 3. Based on the CV curves and stability test, the high degradation activity revealed the kinetically beneficial regeneration of FeII/MnII in Fe/Mn@CC and activation of H2O2. The electron transfer between FeII/III and MnII/III, together with the direct FeII/MnII regeneration on the cathode, could markedly promote the H2O2 utilization, and eventually lead to MIT degradation.
