Special Issue Information

Dear Colleagues,

Advanced oxidation processes (AOPs) are a one of the most studied group of technologies for water and wastewater treatment. The biggest potential comes from catalytic processes providing enhanced conversion of external oxidants to active radical species, increased reaction rates, and complete mineralization of the degraded organic compounds. In addition to catalytic AOPs based on the formation of hydroxyl radicals from oxygen, hydrogen peroxide and ozone, as well as photocatalytic approaches, recently, the attention of scientists has predominantly been focused on catalysts for the activation of persulfates (sulfate radicals-based AOPs—S-AOPs) as well as catalysts for cavitation-based AOPs.

This Special Issue is dedicated to novel achievements in the field of catalytic advanced oxidation processes. The contributions should be related to the listed topics:

  • Catalytic processes in water and wastewater treatment
  • Developments in Fenton-like AOPs
  • Activation of Persulfates for AOPs
  • Formation of sulfate radicals
  • Catalytic cavitation-based AOPs (hydrodynamic cavitation and acoustic cavitation)
  • Sonocatalysts
  • Catalytic ozonation
  • Photocatalysts—including visible light and UV applications
  • Catalytic wet air oxidation (CWAO)
  • Catalytic–electrochemical AOPs
  • Carbon catalysts for AOPs
  • Nanocatalysts
  • Risk of by-product formation during water and wastewater treatment
  • Developments in process control of catalytic AOPs (analytical methods, chromatographic, and spectroscopic techniques)
  • Methods of catalysts characterization
  • Post-process assessment of effluents toxicity
  • Application of nanobubbles in AOPs
  • Economic analysis of catalytic AOPs application and catalysts life cycle assessment (LCO)
  • Industrial catalytic wastewater treatment
  • Modelling and optimization of catalytic processes
  • Green chemistry aspects in catalytic water and wastewater treatment

Photocatalytic Performance of Electrospun Silk Fibroin/ZnO Mats to Remove Pesticide Residues from Water under Natural Sunlight

We have evaluated the efficiency of silk fibroin (SF) coated with ZnO nanoparticles in the photocatalytic disappearance of one acaricide (etoxazole) and three fungicides (difenoconazole, myclobutanil and penconazole) in water exposed to sunlight irradiation. Electrospun SF/ZnO mats were successfully synthesized by electrospinning technique and characterized by XRD, FE-SEM, XPS, XDS, FTIR, and BET. The influence of catalyst loading on the degradation kinetics of the different pesticides was examined in order to gain knowledge of maximum degradation efficiency. A significant increment in degradation rates was observed with the addition of ZnO. SF mats with 25 mg of ZnO were finally selected since no significant differences (p < 0.05) were detected when the loading was enlarged from 25 to 50 mg for the majority of the compounds. In the experimental conditions, the half-lives ranged from 33 min to 93 min for etoxazole and myclobutanil, respectively. The comparison of SF materials coated with similar amount of TiO2 and ZnO showed that the later was slightly more efficient to remove pesticide residues. Hence, the use of electrospun SF/ZnO nanostructures would provide an environmentally friendly approach with photocatalytic activity to be applied in the reclamation of water polluted by pesticides.
