Summary: In this study, Cu-MOF and oxygen vacancy were used to improve the 1,4-dioxane (1,4-D) photocatalytic degradation efficiency of Bi2O3. The incorporation of Cu-MOF increased the specific surface area, pore structure, and reduced particle size of Bi2O3, leading to enhanced visible light utilization and improved photoelectron transfer rate. However, oxygen vacancies negatively affected the photocatalytic activity of Bi2O3. Therefore, the construction of heterojunctions using Cu-MOF can significantly enhance the efficiency of 1,4-D degradation, making Bi2O3/Cu-MOF a promising photocatalyst.

Summary: This paper introduces a novel Li-O2 battery electrocatalyst, a surface-functionalized CoP/Ti3C2Tx composite. The composite exhibits optimized electronic structure and active electrons, which enhance the efficiency of electrochemical reactions. The accordion shaped Ti3C2Tx with large specific surface area and excellent electronic conductivity enables sufficient exposure of active sites and Li2O2 deposition. Transition metal phosphides provide more active catalytic sites and exhibit good electrocatalytic performance. As an electrocatalyst in Li-O2 battery, the CoP/Ti3C2Tx composite achieves high specific discharge capacity and low overpotential, outperforming CoP and Ti3C2Tx individually. The application of transition metal phosphides and MXene in Li-O2 battery not only demonstrates higher cycling stability of the prepared composite, but also points out the direction for improving their electrochemical performance.

Summary: A new magnetically assembled electrode (MAE) was formed by fixing magnetic activated carbon particles (Fe3O4/active carbon composites) as auxiliary electrodes (AEs) on the surface of Ti/Sb-SnO2 foil using a NdFeB magnet. Characterizations and electrochemical tests were conducted to evaluate the electrochemical properties and oxidation performances of the MAE towards different simulated wastewaters. The results showed that the loading amounts of AEs significantly influenced the electrochemical properties, removal efficiency of target pollutants, and accumulation of intermediate products in the wastewater treatment process.

Summary: In this work, titanium (Ti4+) doping was optimized in CoMoO4 nanorod anode material to improve its intrinsic behavior for lithium-ion battery applications. Among the different doping concentrations, 20 wt % Ti-doping showed the best performance in terms of reversible capacity, cycling stability, and rate capability. Ti4+ doping introduced additional electrons and vacancies in the CoMoO4 crystal lattice, leading to enhanced electronic conductivity and diffusion rate of Li+ ions. The 20 wt % Ti-doped CoMoO4 anode exhibited superior electrochemical performance due to the optimum doping concentration and synergistic effect of TiO2 nanoparticles.

Summary: In membrane bioreactors (MBRs), N-acyl homoserine lactones (AHLs)-related quorum sensing (QS) is identified as a major cause of biofouling during wastewater treatment. This study investigates the direct injection of unentrapped Rhodococcus sp. BH4 strains into a probiotic QQ MBR, and finds that it effectively mitigates biofouling but leads to increased fouling rates when injection is halted. The QQ bacteria degrade AHLs, inhibit soluble carbohydrates and protein generation, and increase cell-bound extracellular polymeric substance concentrations. They also impact the bacterial abundance and microbial composition.

Summary: Nitrogen-doped (NAC), sulfur-doped (SAC), and nitrogen/sulfur co-doped activated carbon (NSAC) were used to activate peroxydisulfate (PDS) for degrading acid orange 7 (AO7). The NSAC/PDS system showed the highest degradation performance. The degradation of AO7 was attributed to non-radical pathways, and the doping of N or S resulted in the generation of pyridinic N and thiophenic S, creating more edge defects and active sites for enhanced catalytic degradation.

Summary: The development of a bifunctional photocatalyst that can be utilized for both energy conversion and environmental remediation is of practical significance. A bifunctional S-scheme hybrid photocatalyst comprising CdS nanorods and BiOIO3 nanosheets was developed for efficient antibiotic degradation and CO2 reduction. The exceptional performance of the hybrid catalyst can be attributed to the effective S-scheme charge transfer process, which accelerates photoexcited charge transfer and ensures high charge separation and strong redox power. This study provides insight into the rational design of bifunctional S-scheme hybrid photocatalysts for CO2 reduction and pollutant degradation.

Summary: This study synthesized a series of biochar-like hyper-crosslinked polymers (HCPs) with different amounts of phenolic hydroxyl groups to investigate the roles of key surface properties of biochar in transforming pollutants. The results showed that increasing amounts of hydroxyl groups on HCPs led to higher production of hydroxyl radicals. Batch degradation experiments indicated that HCPs with the lowest amounts of hydroxyl groups showed the highest degree of trichlorophenols (TCPs) degradation, while HCPs with the highest hydroxyl group abundance exhibited the lowest degree of TCP degradation.

Summary: Quorum quenching (QQ) has been successful in preventing biofouling in membrane bioreactors (MBRs) using isolated QQ bacterial strains. However, the effect of QQ on the microbial population is still not fully understood. This study analyzed the microbial population in MBRs over an extended period under different conditions and found that QQ treatment did not significantly affect the structure and diversity of the microbial community. The research also provided insights into the role of bacterial QQ in reducing MBR biofouling and its underlying mechanisms.

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.
