Design of highly efficient porous carbon foam cathode for electro-Fenton degradation of antimicrobial sulfanilamide

Electro-Fenton degradation of a ternary pharmaceutical mixture and its application in the regeneration of spent biochar

“…6) and concentrations of 0.447, 0.126 and 0.367 mg/g of VLX, TRZ and FLX were detected in the biochar after 90 min of treatment. Therefore, the limitation of the electro-Fenton process in the absence of electrolyte was revealed, which could be attributed to the necessity for a supporting electrolyte to promote the electrocatalytic reduction of oxygen to hydrogen peroxide [39] and indicate its role decreasing the ohmic resistance of the solution [40]. In addition, as reported in the literature, sodium sulphate could not be considered inert due to the formation of persulfate, which could collaborate in the degradation of organic pollutants present in the solution [41,42].…”

“…This trend is consistent with previous reports in the literature, in which several real water matrixes were used. In all cases, the low degradation rates detected are attributed to the presence of scavenger compounds that react with the available free radicals and compete with the added pollutants due to the hydroxyl radical being a non-selective oxidant [35,39].…”

Porous Carbon Substrate Improving the Sensing Performance of Copper Nanoparticles Toward Glucose

“…With the special three-dimensional framework structure [24], porous carbons not only possess abundant binding sites to promote the dispersion of metal active centers, but also provide a larger specific surface area that improves the accessibility of electrons and reactive substances [25][26][27]. In recent years, porous carbons have been recognized as a type of promising modification and substrate materials, which can greatly enhance the electrochemical sensing activity of metal materials.…”

Management of solar energy to power electrochemical wastewater treatments

“…Nevertheless, the drawbacks of green energies rule a continuous operation out. To solve this problem, many groups have tested the performance of electrochemical remediation technologies directly coupled with traditional batteries (Lead-acid batteries) directly charged by green energies [36][37][38][39]. Nevertheless, a direct powering by batteries may lead to a huge waste of energy due to the efficiencies of energy conversion.…”
