Fe, Co, Ni nanocrystals encapsulated in nitrogen-doped carbon nanotubes as Fenton-like catalysts for organic pollutant removal

Direct fabrication of lamellar self-supporting Co3O4/N/C peroxymonosulfate activation catalysts for effective aniline degradation

“…1, and the combination of functional spinel Co 3 O 4 crystals, Co-N 4 moieties, and carbon N-doped was achieved in these compounds at a time, which enhances the AOPs-SRs performance and avoids cobalt species agglomeration during thermal oxidation. As a matter of fact, similar materials, such as dicyandiamide [37], polyvinylpyrrolidone [38], 2-methylimidazole [39], melamine [40,41] and so on, have been chosen as a C/N precursor. These studies further evidence that this synthetic route is feasible.…”

Strongly Coupled g‐C3N4 Nanosheets‐Co3O4 Quantum Dots as 2D/0D Heterostructure Composite for Peroxymonosulfate Activation

“…As one of the most popular AOPs, the∙OH generated from H 2 O 2 through the homogeneous/heterogeneous Fenton reaction is highly recognized to degrade various organic compounds; however, disadvantages such as acidic pH condition, relatively low efficiency, and instability of H 2 O 2 remains a problem . Compared to ∙OH, SO 4 ∙− based AOPs is being increasingly adopted by the following reasons: i) SO 4 ∙− has a higher redox potential (SO 4 ∙− : ≈2.5–3.1 V vs OH: ≈1.9–2.7 V) for pollutants decompose; ii) SO 4 ∙− can be generated from peroxymonosulfate (PMS), which can be easily activated in comparison with H 2 O 2 due to the asymmetric molecular structure . Transition metal oxides (Co, Cu, and Mn, etc.)…”

Fe Oxides Loaded on Carbon Cloth by Hydrothermal Process as an Effective and Reusable Heterogenous Fenton Catalyst

“…Methanol is a commonly used radical scavenger to determine the contribution of the hydroxyl radical during heterogeneous Fenton-like reaction (KHO•=1.2 − 2.8 × 10 9 M −1 •s −1 ) [32,35,36]. As shown in Figure 6A, the addition of 0.1 M and 0.5 M methanol reduced the decolorization rate by 18.2% and 38.7%.…”
