Summary: In this study, core-shell tetracycline hydrochloride-molecularly imprinted polymers (MIPs) were prepared for the first time using a magnetic covalent organic framework (Fe3O4@Tppa-2) as a substrate. The introduction of Fe3O4@Tppa-2 into the molecular imprinting system shortened the adsorption equilibrium time of MIPs. The MIPs showed a maximum adsorption capacity of 87.50 mg/g and reached adsorption equilibrium in 14 minutes. They were successfully used as magnetic solid-phase extraction sorbents in combination with high performance liquid chromatography for the detection of tetracycline in pork, chicken, and chicken liver.

Summary: Oxygen can generate reactive oxygen species in photocatalysis, promoting organic matter's mineralization. Therefore, enhanced oxygenation of the photocatalytic degradation system will help improve photocatalytic degradation efficiency. This study developed a novel high-gravity photocatalytic degradation method, which leverages the robust gas-liquid mass transfer capability of a supergravity rotating bed to realize the enhanced oxygenation of the photocatalytic degradation system. Specifically, this study used graphitic carbon nitride as the catalyst and tetracycline hydrochloride as the model pollutant. The effects of packing thickness, catalyst concentration, liquid flow rate, rotor speed, gas flow rate, and initial pH value on photocatalytic degradation performance were investigated. The results showed that the degradation rate of tetracycline hydrochloride reached 84.6 % under the optimal conditions of the rotating packed bed, which was 14.8 % higher than that of the traditional photocatalytic degradation process.

Summary: The photocatalytic performance of g-C3N4 for the removal of antibiotics from wastewater can be enhanced by hydrothermal dissociation and subsequent calcination reconstitution, resulting in a higher specific surface area, efficient charge separation, and strong redox ability. The optimized sample (CN-C-12) shows a 4.5 times higher apparent kinetic constant (k) for tetracycline hydrochloride (TCH) degradation compared to pristine g-C3N4, with stable cycling photo-catalytic activity. Superoxide radicals (& BULL;O2-) and singlet oxygen (1O2) are identified as the primary reactive species in the photocatalytic degradation of TCH.

Summary: La2S3/SN-biochar composites were prepared by modifying S,N-codoped biochar with La2S3, which significantly improved the adsorption and photocatalytic activities for tetracycline hydrochloride removal. The optimal 3c-La2S3/SN-biochar with a La content of 15.43 wt% and an N content of 0.49 wt% exhibited the highest TCH removal efficiency. However, long-term photo-corrosion led to decreased adsorption-photocatalytic efficiency and decreased adsorption capacity.

Summary: Compared with traditional hydrothermal synthesis, microwave-assisted synthesis offers the advantage of faster and more energy efficient synthesis. In this study, the microwave-assisted hydrothermal method was used to synthesize MoS2/BiVO4 hetero-junction photocatalyst, resulting in a spherical structure in the nanorange. The heterojunction significantly improved the photocatalytic performance, with a degradation rate of tetracycline hydrochloride (TC) of 93.7% in 90 min. The active species capture experiments indicated that ·OH, ·O-2(-) and h(+) active species played a major role in the degradation of TC. Microwave technology provides a quick and efficient method for synthesizing MoS2/BiVO4 heterojunction photocatalysts.

The catalyst exhibited high CO Faradic efficiency and low Tafel slope compared to single-atom Fe catalyst. Density functional theory calculations revealed that the neighboring Fe-Fe centers in the Fe2N6 site facilitated CO2 activation and decreased the reaction barrier for CO desorption.

Summary: By incorporating molybdenum sulfide (MoS2) nanosheets and applying external electrical assistance, both the 2D channel and charge density of reduced graphene oxide (rGO) membranes were regulated to enhance water flux and salt rejection. The resulting rGO/MoS2 membranes exhibited expanded nanochannels, resulting in significantly increased water permeance. In addition, the high capacitance and negative potential of the membranes contributed to improved rejection rates for NaCl and Na2SO4 ions. This study provides new insights for the design of membranes with high water flux and salt rejection efficiency.

Summary: Membrane separation is widely used in water and wastewater treatment due to its cost-effectiveness, ease of operation, and high efficiency. However, current membranes face challenges in balancing selectivity and permeability, as well as dealing with membrane fouling. Recent studies have focused on developing high-performance membranes based on carbon nanomaterials, such as carbon nanotubes and graphene, to improve water and wastewater treatment. These carbon nanomaterial-based membranes demonstrate enhanced permselectivity and fouling resistance under electrochemical assistance, thanks to their good electrical conductivity. This review summarizes the progress in the preparation, mechanisms, and applications of electroconductive nanocarbonaceous membranes for water purification and wastewater treatment, aiming to enhance the fundamental understanding of combining membrane separation and electrochemistry. The review covers methods for preparing electroconductive membranes, such as carbon nanotube membranes and graphene membranes, as well as the underlying mechanisms for the improved permselectivity, antifouling, and regeneration performance achieved through electrochemical processes. The review also discusses practical limitations of membrane/electrochemistry systems and proposes possible solutions.

Summary: Developing efficient and interference-tolerant catalysts for practical use in catalytic ozonation process is challenging. In this study, a surface Vo-rich catalyst was prepared by doping Co into zinc ferrite spinel, showing efficient mineralization of recalcitrant organic pollutants. The removal of contaminants was mainly attributed to nonradical-based oxygen species, *O, rather than traditional hydroxyl radicals, •OH. The Vo-driven nonradical catalysis exhibited high resistance to coexisting ions and excellent performance in actual wastewater treatment, providing a novel strategy for efficient mineralization of pollutants in complicated water matrices.

Summary: Electrochemically reducing nitrate to ammonia is an efficient method to address nitrate pollution. However, controlling the selectivity and kinetics of ammonia production remains a challenge. In this study, a single-atom Cu catalyst was developed for selective and efficient nitrate reduction, achieving high Faradic efficiency and ammonia selectivity. DFT calculations revealed the underlying mechanism, demonstrating the superiority of the single-atom Cu catalyst over Cu nanoparticle catalyst. This research provides a strategy for designing electrocatalysts for efficient and selective ammonia production via nitrate reduction.

Summary: In this study, it was found that electrochemical treatment can expand the restacked regions of reduced graphene oxide (rGO) membranes, leading to the formation of ultrafast water transport nanochannels. The expansion is driven by hydrogen bond interactions between water molecules and electrochemically produced hydroxyl groups on the edges of rGO nanosheets. The treated rGO membranes exhibit a permeance 2 orders of magnitude higher than pristine rGO membranes and about 3 times higher than graphene oxide membranes. Additionally, the rGO membranes also show higher ionic/molecular rejection performance due to their smaller average pore size.

Summary: As a major driver of global methane production, methanogens are exposed to an environment filled with dynamic electromagnetic waves, which may induce electromotive force (EMF) to potentially influence methanogen metabolism. This study found that exposure to a dynamic magnetic field increased biogas production through induced EMF. The methane emissions from sediments increased by 41.71% when exposed to a dynamic magnetic field with an intensity of 0.20 to 0.40 mT. The EMF accelerated the respiration of methanogens and bacteria, leading to enhanced microbial metabolism.
