“…This technique has been employed for simultaneous wastewater treatment and energy recovery. [1][2][3] The main advantage of Fenton reactions is the involvement of ferrous iron and hydrogen peroxide, [4][5][6][7][8][9][10][11][12][13] and this has been proven to be effective over other conventional wastewater treatment methods. 14 Although the BEF system is very simple, the high cost of hydrogen peroxide and the undesirable recycling of ferrous iron are the major drawbacks for large-scale application in wastewater treatment.…”

Summary A novel bioelectro‐Fenton microbial fuel cell (BEF‐MFC) cathode has been fabricated by modification of electrode using multi‐processing of nitrogen‐doped carbon (NDC)/nano‐Fe3O4 method with the aims of cost‐effectiveness, high oxygen reduction reaction (ORR) efficiency, and power performance enhancement. In this study, BEF‐MFC with carbon cloth (CC) cathode pyrolyzed with NDC‐M100/Fe3O4 at 700°C achieved higher ORR activity compared with the commercial Pt/C under same operational conditions. It also exhibited excellent crystalline structure according to high‐resolution transmission electron microscope (HRTEM) analysis. Moreover, using NDCN/Fe3O4 can facilitate further Fenton‐like reaction for the treatment of wastewater. Chemical oxygen demand (COD) removal efficiency of the reactor was 78% with maximum power density of 1.57 W/m3 in 216 hours. Thus, an innovative multi‐processing method with feasibility for enhanced wastewater treatment and improved power performance of the MFC was investigated. This can be effectively applied in related alternative energy production techniques and bio‐electrochemical systems in the future.

The objectives of this present study are to synthesize iron oxide and zinc oxide nanoparticles from different concentrations of Sesbania grandiflora leaf extract (5-20%) using zinc nitrate and ferrous chloride as precursor materials and synthesized nanoparticles were characterized using UV-visible spectrometer, FTIR, X-ray diffraction, and SEM. The results showed that synthesized zinc oxide and iron oxide nanoparticles exhibited UV-visible absorption peaks at 235 nm and 220 nm, respectively, which indicated that both nanoparticles were photosensitive and the XRD study confirmed that both nanoparticles were crystalline in nature. In addition, FTIR was also used to analyze the various functional groups present in the synthesized nanoparticles. The SEM results reveal that zinc oxide nanoparticles were spherical in shape and having the particle size range of 15 to 35 nm whereas the iron oxide nanoparticles were nonspherical in shape with the size range of 25 to 60 nm. Application of synthesized nanoparticle on seafood effluent treatment was studied.

“…According to the results of the pH effect experiments, it can be concluded that weak acidic and neutral pH values do not show considerable effect on the degradation of ethylparaben. The pH value effects the formation of hydroxyl radicals and degradation efficiency and in the photo-Fenton-like processes, the maximum degradation efficiency is obtained around a pH 3 [23]. For example, Petala A. et al carried out a study on the degradation of ethylparaben over an N-TiO2 catalyst in the presence of solar light and this study showed that the highest degradation efficiency was performed at the acidic medium and there was no considerable degradation at the neutral and alkaline medium [24].…”

The degradation of ethylparaben using photo-Fenton-like oxidation was investigated in the presence of a BiFeO3 catalyst. Firstly, the catalyst was synthesized using the sol-gel method and characterized via BET and FT-IR analyzes and then, a parametric study was carried out in order to determine the optimum reaction conditions for the degradation of ethylparaben. In this context, the effects of catalyst loading, [H2O2]o, pH, and temperature on the degradation were investigated. According to the results, the optimum reaction conditions were determined for a 5 ppm ethylparaben solution as 0.25 g/L catalyst loading, a pH of 3, and 2 mM [H2O2]o and a 97.7% degradation of ethylparaben was accomplished. Iron leaching at the optimum conditions was evaluated as 1.53 ppm and it is lower than the E.U. iron concentration limitation (2 ppm) in the water. The kinetic study was carried out at the optimum reaction conditions at three different temperatures (25, 35, and 45 °C). The degradation of ethylparaben using photo-Fenton-like oxidation fitted the first order reaction kinetic model. The reaction rate constants were determined as 0.041, 0.050, and 0.069 min -1 for 25, 35, and 45 °C, respectively. The activation energy was found as 20.4 kJ/mol.
