Cobalt ferrite nanoparticle-loaded nitrogen-doped carbon sponge as a magnetic 3D heterogeneous catalyst for monopersulfate-based oxidation of salicylic acid

Enhanced degradation of ultra-violet stabilizer Bis(4-hydroxy)benzophenone using oxone catalyzed by hexagonal nanoplate-assembled CoS 3-dimensional cluster

“…Co 3+ @NPCS+ HSO5 -→ Co 2+ @ NPCS + SO5 To further quantitatively distinguish catalytic activities of NPCS and Co3O4 nanoparticle, the corresponding reaction stoichiometric efficiencies (RSE) were then determined as RSE has been increasingly adopted to access catalytic activities of catalysts for activating Oxone to degrade pollutants as follows [45,46]:…”

Investigating crystal plane effect of Co3O4 with various morphologies on catalytic activation of monopersulfate for degradation of phenol in water

“…To further quantify degradation efficiencies by Co3O4-NP/MPS under various conditions, their reaction stoichiometric efficiencies (RSE) were then calculated as RSE has increasingly adopted to quantify catalytic activity for activating MPS by catalysts via the following equation (Eq. 4) [51]:…”

Graphitic carbon nitride and carbon nanotubes modified active carbon fiber cathode with enhanced H2O2 production and recycle of Fe3+/Fe2+ for electro-Fenton treatment of landfill leachate concentrate

“…8 Due to the high positive charge density of carbon atoms, carbonaceous materials generally have a high inclination toward the oxygen “end-on” adsorption mode, which is beneficial for preventing the destruction of the O–O bond in adsorption. 9 Until now, there have been a multitude of studies on using different carbonaceous materials as the cathode, including graphite, 10 reticulated vitreous carbon, 11 carbon sponge, 12 graphite felt, 13,14 active carbon fiber, 15–17 and a carbon/PTFE composite electrode. 18,19 Among these materials, active carbon fiber with a three-dimensional porous structure features a large specific surface area, abundant micropores, chemical stability, high hydrogen evolution potential and the efficient cathodic regeneration of Fe 2+ .…”
