Enhanced decomposition of dimethyl phthalate via molecular oxygen activated by Fe@Fe2O3/AC under microwave irradiation

Fe3O4/multi-walled carbon nanotubes as an efficient catalyst for catalytic ozonation of p-hydroxybenzoic acid

“…2). Similar results were also observed by other researchers in catalytic ozonation or Fenton-like reaction, the catalyst deactivation was attributed to several factors, including the poisoning of the active catalytic sites by absorbed organic species, and the decrease in the catalyst specific area (Chen et al 2012). In addition, the decrease in the activity was also influenced by the adsorption of intermediates.…”

Preparation and characterization of a novel KOH activated graphite felt cathode for the electro-Fenton process

“…Both surface chemistry and structure were studied, and the electrocatalytic activity for ORR was investigated. Moreover, dimethyl phthalate (DMP) was chosen as the main model organic pollutant to assess the performance of the activated GF as EF cathode, because it has been listed as one of the priority pollutants in many countries, and has been used in rapid performance assessment of some AOPs including EF reactions [38][39][40][41][42].…”

Magnetic nanosized calcium ferrite particles for efficient degradation of crystal violet using a microwave‐induced catalytic method: insight into the degradation pathway

“…The highest MW catalytic degradation efficiency of CaFe 2 O 4 can be explained as follows: under microwave irradiation, the surface of CaFe 2 O 4 particles can produce a large number of ‘hot spots’ (with temperatures reaching >1473 K) . Meanwhile, the electrons in CaFe 2 O 4 could oscillate under microwave excitation, and the ‘hot‐spots’ could speed up the movement of electrons in CaFe 2 O 4 to excite electrons and therefore generate electron/hole pairs as with visible light (Equations ). Electrons are transferred to the Fe3d orbital to form ≡ Fe(II) (Equation ), thus the lifetime of the holes (h + ) is prolonged in the transfer process.…”
