Summary: In this study, modified natural zeolite and modified magnetic zeolite were synthesized and found to have excellent phosphorus adsorption and passivation capabilities. The addition of these materials can effectively control the release of pollutants and transform unstable phosphorus into stable phosphorus. Moreover, these materials can reduce the amount of bioavailable phosphorus in sediments. The magnetic zeolite, in particular, shows better effects and can be used as a passivator for internal pollution control.

Summary: The regenerable magnetic AL/Fe3O4/La(OH)(3) adsorbents showed high adsorption capacities for phosphate and glyphosate, with Fe3O4 and La(OH)(3) enhancing the adsorption process. The adsorbents can be rapidly separated with an external magnetic field due to the magnetic properties of Fe3O4, and 89% of the adsorption capacity remained after four adsorption-desorption cycles, indicating their potential for effective and reusable phosphate and glyphosate removal.

Summary: Lanthanum modified zeolite (LMZ) has shown to be an effective agent for controlling internal phosphorus load in lakes, and its performance in co-sequestration of phosphorus and zinc was investigated in this study. The results indicated that the removal rate of zinc increased with higher concentrations of co-existing phosphate, while the presence of zinc had minimal impact on phosphate adsorption. Increasing the background NaCl concentration inhibited zinc removal, suggesting that part of zinc was physically adsorbed by the zeolite fraction of LMZ.

Summary: The removal of phosphorus (P) is crucial for protecting the environment. This study investigated the mechanism of P removal by La-containing materials and evaluated the effectiveness of a new material, La-2(CO3)(3(s)), in removing P from various aqueous systems, including municipal wastewater. The results showed that P removal occurred mainly through the precipitation of LaPO4(s). La-2(CO3)(3(s)) exhibited selective removal of P over other anions and had a relatively low solubility, making it a suitable material for P sequestration. Understanding the mechanism of P removal and finding effective materials are important for mitigating eutrophication.

Summary: The synthesis temperature of lanthanum carbonates (LCs) affects their ion exchange capacity and P adsorption capacity at low concentrations. LC-80 and LC-90 are novel LC species with higher ion exchange capacity and form inner-sphere complexes with P through ion exchange. LC-100 has lower ion exchange capacity and adsorbs P through ion exchange and electrostatic attraction. The resistance to pH and co-existing ions is greater for LC-80 and LC-90, while LC-100 is more susceptible. A five-cycle regeneration operation demonstrates the recyclability and reusability of LCs, with LC-90 showing the highest P adsorption capacity at low concentrations. The cost-effective performance of LC-90 makes it a promising adsorbent for low-level P removal. Overall rating: 8.5/10.

Summary: This review focuses on the development and application of lanthanum-engineered biochar (LEB) in environmental applications, highlighting the preparation processes, dominant lanthanum species, and adsorption capabilities of LEB. LEBs are prepared through pre-/post-doping methods, involving precipitation, gelation, and calcination. The dominant lanthanum species in LEBs is La(OH)3, formed through precipitation of La ions with various bases. LEBs exhibit high efficiency in the adsorption of phosphate, arsenic, antimonate, and fluoride ions, attributed to the strong affinity of lanthanum to oxyanions and Lewis hard base.

The results showed that pumice-amended mixtures (75%P-25%Z) had the highest phosphorus adsorption capacity, indicating that pumice was more effective than zeolite in improving phosphorus removal efficiency of the substrate materials. It was concluded that pumice could be reliably used for nutrient removal from wastewaters.

Summary: In this study, metallic cobalt supported on nitrogen-doped carbon material was used as an efficient catalyst for the oxidative esterification of 5-hydroxymethylfurfural (HMF) to furan-2,5-dimethylcarboxylate (FDMC). The carbonization temperature had a significant impact on the morphology and structure of Co/N-C samples. Co/ N-C calcined at 900 degrees Celsius showed the best catalytic performance, with a 73.8% FDMC yield at a 91.7% HMF conversion rate measured at 130 degrees Celsius for 20 hours with K2CO3 under 1 MPa O-2. The catalytic activity of Co/N-C was enhanced by the synergistic effect between metallic cobalt and nitrogen-doped carbon material. A reaction mechanism for FDMC formation was proposed.

Summary: Pd/SSZ-13 catalysts were investigated for the simultaneous storage of NO and C3H6 at 100 degrees C. The effects of the state of Pd species on co-adsorption and release were studied under simulated exhaust conditions. The results showed that the NO storage capacity at 100 degrees C was enhanced by simultaneous NO + C3H6 adsorption. DRIFTs results showed that Pd2+ provides the adsorption sites for NO + C3H6 to form Pd2+(NO) (C3H6), which alleviates the inhibition effect of H2O on NO adsorption on Pd ions. The different release behaviors of NO + C3H6 are discussed based on the chemistry of NO and C3H6 adsorption and the effect of intermediate CO.

Summary: A bi-functional catalytic perovskite LaNi0.5Co0.5O3 (LNCO) is utilized as the cathode in a high-efficiency Li-O2 battery with a molten nitrate salt electrolyte at 160 degrees C. This LNCO cathode exhibits stable low charge-discharge overpotential and high energy efficiency over 100 cycles. The discharge product, Li2O, has a porous and fluffy morphology, facilitating the transfer of oxygen and other intermediate species. Li2O as a discharge product enables a higher theoretical specific energy density compared to Li2O2 in ambient temperature Li-O2 batteries.

Summary: A Sn-doped Ce0.8Sm0.2O2_delta (SDC) supported Sn-Ni alloy anode was designed and prepared through a dual-modification strategy. The substitution of Sn improved the mobility of lattice oxygen in SDC, and Sn exsolves from the oxide phase to form intermetallic compounds with Ni after reduction. The composite anode showed unprecedented activity in the electrochemical oxidation of H2 and CH3OH, with high power densities achieved using these fuels. This work opens a new path for the design of high-performance SOFC anodes.

Summary: The construction of Z-scheme graphitic carbon nitride-titanium dioxide nanotubes (C3N4-TNT) is beneficial for optimizing the band structure and improving the efficiency of photoelectrochemical water splitting cells. However, the narrow operating potential window of 0-1.23 VRHE limits the understanding of the C3N4-TNT electrode. This study applied a broader potential window of -0.5-2.5 VRHE to analyze the effect of external electrons and simulated sunlight on C3N4-TNT@Ti, revealing enhanced photocurrent density and potential for advanced water oxidation/reduction.

Summary: Fast and durable lithium storage in entropy-stabilized Fe0.4Ti1.6Nb10O28.8 (FTNO) is achieved by tuning entropy via Fe substitution. Increasing the entropy leads to reduced grain size and a shorter Li+ pathway along diffusion channels. The increased entropy also stabilizes the lithium intercalation channel by decreasing expansion along the a-axis.

Summary: Photocatalytic N-formylation of amines with CO2 is achieved using a black TiO2-supported Cu photocatalyst prepared through a solvothermal method. Reduction with H-2 results in the formation of Cu nanoparticles and oxygen vacancies on the surface of the photocatalyst, enhancing the photocatalytic activity. A 100% conversion and an 81% yield of N-methylformanilide are achieved after 9 hours of radiation. The amount of NaBH4 and the pressure of CO2 significantly affect the activity and selectivity of the photocatalytic process.

Summary: By functionalizing with imidazole and grafting with an oligoether chain, a ferrocene derivative 1-ferrocenylmethyl-3-(2-(2-(2-methoxyethoxy)ethoxy)ethyl)imidazolium-bis(trifluoromethylsulfonyl)imide (FcMITEGTFSI) is designed. The imidazolium cationic group induces a positive shift in redox potential of the ferrocene core while ensuring the stability of the active species; the flexible oligoether side chain renders the molecule liquid at room temperature and miscible with acetonitrile solvent. The flow battery exhibits robust cycling stability, with an overall discharge capacity retention of approximately 95.5% after 200 cycles, corresponding to a capacity retention of approximately 99.98% per cycle at 25 mA cm(-2) with 0.1 M electrolyte.
