Summary: The COVID-19 pandemic has accelerated the development of wastewater purification technologies, such as electro-Fenton. Through careful investigation, we have found that a Fe-doped ZnO electrode can achieve a Faradaic efficiency of 78% for H2O2 electrogeneration at a voltage of 3.2 V vs. RHE, and maintain a current density of 10 mA cm(-2) for at least 6 hours. This electrocatalytic process can generate hydroxyl radicals, which can be used for the treatment of contaminated water. Additionally, this electrode system can effectively remove microbial contamination, with a killing rate of up to 99%.

Summary: Electro-Fenton (e-Fenton) is a promising method for wastewater treatment by generating powerful .OH through the decomposition of electro-generated H2O2 catalyzed by Fe2+. However, developing a catalyst capable of simultaneously producing H2O2 and accelerating Fe2+ regeneration remains a challenge. In this study, a hollow porous carbon sphere catalyst (HPCS) was developed to enhance H2O2 generation and Fe3+/Fe2+ cycling by constructing an electron-rich microenvironment via surface curvature regulation. The HPCS-TPOS catalyst with a larger curvature structure showed higher Fe2+ regeneration efficiency (35.5%) compared to the HPCS-S catalyst (22.8%). The HPCS-TPOS also exhibited a higher H2O2 production rate (47.2 mmol L-1 h-1) surpassing state-of-the-art e-Fenton catalysts. These findings provide new insights into the design of efficient catalysts for wastewater treatment by regulating curvature structures.

Summary: This study evaluated the electrochemical oxidation of gaseous streams polluted with benzene, toluene, and p-xylene using a jet mixer and electrochemical cell device. The technology achieved an efficiency of 14% in hydrogen peroxide production at atmospheric pressure and 12 degrees C. Results demonstrated the effectiveness of electrochemically assisted absorption for treating these polluted streams. In particular, the electro-Fenton assisted absorption (EFAA) showed higher removal efficiencies compared to electrolytic assisted absorption (ELAA) and physical absorption (PA) due to the promotion of Fenton reagent formation.

Summary: This study investigates the discoloration of a model dye using an electroFenton process and ultrasound induced cavitation. The results show a strong synergistic interaction between the electrochemically induced discoloration kinetics and the ultrasound promoted cavitation. Electrochemical impedance spectroscopy (EIS) study reveals significant effects of ultrasonic cavitation at the carbon cathodes electrolyte interphase, while the effect is relatively negligible in the bulk of the solution and in the electrolyte pores of the carbon electrode. The study suggests the future development of novel wastewater treatment processes using air saturated solutions to overcome the low solubility of O2 that limits traditional electro-Fenton approaches.

The Janus ECM showed a higher removal rate and lower energy consumption compared to the traditional ECM assembly. The enhanced PMS electro-activation efficiency was achieved through singlet oxygenation intensification and direct usage of cathode for direct electron transfer (DET) mediation. The Janus ECM improved mass transfer and spatial confinement to enhance water decontamination efficiency.

Summary: Fine-tuning the geometric and electronic structure of catalytic metal centers via N-coordination engineering allows for the selective electrocatalytic activation of O-2 to O-1(2). Through a coordination modulation strategy, fluidic single-atom electrodes are synthesized, achieving >98% selectivity towards O-1(2) generation. The use of end-on adsorption of O-2 onto Cr-N-4 sites lowers the activation energy barrier, promoting the breakage of Cr-OOH bonds and the formation of (OOH)-O-center dot intermediates. The flow-through configuration of the fluidic electrode enhances mass transport and charge transfer, resulting in improved performance compared to batch reactors.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
