Synthesis and Application of MnO2/Exfoliated Graphite Electrodes for Enhanced Photoelectrochemical Degradation of Methylene Blue and Congo Red Dyes in Water

Controllable growth on nano-graphite-supported ZrO2–MnOx bimetallic oxides for electrocatalytic antibiotic degradation: mechanism to boost the Mn3+/Mn4+ redox cycle

“…The D band represents C atom lattice defects, while the G band represents the in-plane stretching vibration of C atom sp 2 hybridization. 39 The N 2 adsorption–desorption isotherms and pore-size distribution of the nano-G, MnO 2 /nano-G, and ZrO 2 –MnO 2 /nano-G composite electrodes, as shown in Fig. 3d, are typical type IV isotherms with H 3 hysteresis loops, signifying a typical mesoporous material with uneven pore size distribution.…”

“…It can be inferred that the layer spacing of nano-G is small, and there is a highly stacked ordered graphite layer structure. For the MnO x /nano-G composites, the distinctive diffraction peaks of MnO 39 The N 2 adsorption-desorption isotherms and pore-size distribution of the nano-G, MnO 2 /nano-G, and ZrO 2 -MnO 2 /nano-G composite electrodes, as shown in Fig. 3d, are typical type IV isotherms with H 3 hysteresis loops, signifying a typical mesoporous material with uneven pore size distribution.…”

Barium Hydrogen Phosphate Electrodes for High Electrocatalytic and Photoelectrocatalytic Degradation of Rhodamine B in Neutral Medium: Optimization by Response Surface Methodology

“…Electrochemical advanced oxidation processes (EAOPs) have become one of the most important technologies for environmental remediation [6,7]; they can be used to oxidize nearly all types of organic compounds into harmless products via highly reactive hydroxyl radical (OH • ) having a redox potential of 2.8 V [8][9][10][11][12][13] The advantage of EAOPs is that they are "environment-friendly" as they do not transfer pollutants from a phase to another (as in adsorption) and they do not produce large amounts of hazardous sludge [14][15][16][17]. In EAOPs, the organic pollutants are destroyed by hydroxyl radical OH • which is generated through the electron donors, namely the adsorbed water/OH − groups, or by the superoxide radical ion (O 2…”
