Summary: The electrochemical chlorination of urea to CO2 and N-2 end-products, via active-chlorine-mediated oxidation under nearly neutral conditions, is an effective treatment for medium-concentrated urea-containing wastewater. A novel flow reactor integrated with three-dimensional hierarchically porous Ru/RuO2 architectures anchored on a Ti mesh was designed. The hierarchically macroporous electrode can create sufficient exposure of catalytically active sites and facilitate the microscopic mass transport and diffusion inside the active layer, thereby contributing to the increased removal efficiency of urea-N and ammonia-N.

Summary: Electrocatalytic CO2 reduction reaction (CO2RR) technology has attracted extensive attention for its mild reaction conditions, high energy conversion efficiency, and readily adaptability. However, the lack of highly active catalysts and the selectivity of reduction products remain major challenges. In this study, Bi nanoparticles diffused in nitrogen-doped carbon frame catalysts (Bi@NCFs) were successfully fabricated using an in-situ pyrolysis process. The electrocatalytic test results showed that the Bi@NCFs catalyst exhibited a higher Faradaic efficiency of formate (FEHCOOH) than 79% in the potential range of -0.8 to -1.3 V vs. RHE, with a FEHCOOH as high as 95.70% at -1.0 V vs. RHE. The catalyst also demonstrated excellent durability and stability in H-cell, with FEHCOOH still preserved over 81.3% after a 48-hour stability test.

Summary: In this study, a fast and facile two-step technique to synthesize Ru/RuO2 aerogels for catalyzing overall water-splitting under alkaline conditions is reported. The Ru/RuO2 aerogel exhibits low overpotential for oxygen evolution reaction (189 mV) and hydrogen evolution reaction (34 mV), surpassing RuO2 (338 mV) and Pt/C (53 mV), respectively. When applied at the anode and cathode, the Ru/RuO2 aerogels result in a low potential of 1.47 V at 10 mA cm(-2), exceeding the commercial Pt/C||RuO2 standard (1.63 V).

Summary: Hierarchically porous carbon microspheres with trace amount of encapsulated cobalt exhibit highly active and stable electrocatalytic performance for oxygen reduction reactions (ORR) under wide pH conditions. The catalysts show competitive catalytic activity, superb durability, and methanol tolerance compared to benchmark Pt/C catalyst, even in harsh acidic environments, due to abundant active sites provided by rich surface defects and hierarchically porous structure. The in situ formed cobalt nanoparticles play a crucial role in creating mesopores, high specific surface area, and catalytically active defect sites over the carbon material, further enhancing the ORR activity of the catalysts with negligible cost impact.

Summary: In this study, a facile chemical solution deposition (CSD) strategy is employed to synthesize LaNiO3 (LNO) thin films with a distinct porous structure (P-LNO). The results demonstrate that the presence of the porous structure significantly enhances the OER performance of LNO, requiring an overpotential of 367 mV to achieve 10 mA cm(-2), which is much lower than that of a normal LNO thin film (478 mV). The porous structure provides more exposed active sites and facilitates electron transfer between the catalysts and electrolyte, resulting in an improved OER performance of the P-LNO film.

Summary: Density functional theory calculations are employed to analyze the active sites for CO2 reduction reaction (CO2RR) on TiO2/RuO2 and SnO2/RuO2 alloys. The results show that bridge Ru-Ti and bridge Ti-Ti sites are the active sites for CO formation, while bridge Ru-Ru sites are favorable for formic acid formation. Additionally, substitution of Cu for one bridge Ru atom in a RuO2 overlayer on TiO2 significantly decreases the overpotential for CO and formic acid formation. The knowledge gained from these calculations can be useful for engineering the active sites in order to enhance the catalytic performance.

Summary: In this study, core-shell ZIF-8@RF nanofillers were incorporated into 6FDA-Durene and Pebax 1657 via a physical blending approach to form MMMs, which showed outstanding performance for CO2/CH4 separation due to enhanced interfacial compatibility, CO2 affinity, and the intrinsic characteristics of porous ZIF-8. The CO2 permeability and CO2/CH4 selectivity of the MMMs increased significantly compared to the pristine membrane, and the presence of RF layer in ZIF-8@RF MMMs further improved the CO2/CH4 selectivity. Importantly, both MMMs maintained their excellent separation performance even in the presence of moisture.

Summary: In this study, a sequential Pd-modified polymeric ultrafiltration (UF) membrane was developed for the rapid and economic removal of NDMA. The membrane achieved complete elimination of NDMA using direct electrochemical reduction and Pd-catalyzed hydrogenation. The pre-rejection of interfering substances and the flow-through operation mode improved the stability and reaction kinetics of the membrane, respectively. The combined treatment of the membrane and nanofiltration showed superior performance compared to conventional reverse osmosis in terms of NDMA removal and energy usage. This work provides a new strategy for developing energy-efficient wastewater treatment systems.

Summary: To achieve precise removal of trace FLO in the presence of various high-concentration interferents in water, a novel oxygen vacancy engineered molecular imprinted TiO2 (MI-TiO2-x) cathode material was developed. MI-TiO2-x exhibited enhanced recognition and accelerated interfacial charge transfer due to its molecular imprinted sites and oxygen vacancy, respectively. It demonstrated superior dehalogenation performance, outperforming most recent electrocatalysts, and showed resistance to co-existing interferents. In an electro-reductive and biological coupling system, MI-TiO2-x effectively removed the antibacterial activity of FLO in swine wastewater and eliminated the abundance of FLO resistance genes. This study provides insights into the rational design of noble-metal-free electrocatalysts for the remediation of low-concentration organic halides and highlights the importance of dehalogenation treatment in mitigating ecological risks.

Summary: This study demonstrates the successful incorporation of pyrazole-based metal-organic frameworks (MOF-303) into polymer of intrinsic microporosity (PIM-1) through a physical blending approach, resulting in mixed matrix membranes (MMMs) with remarkable separation performance. The MMMs exhibit improved CO2 permeability and well-maintained CO2/CH4 selectivity compared to unfilled PIM-1 membranes. Notably, the MMMs also display excellent stability, resistance against physical aging, and reinforced resistance to plasticization compared to the control PIM-1 membranes. This research provides a novel approach for the rational design of MMMs in CO2 separation applications.
