Here, we reported a highly efficient nitrate electroreduction (NO3RR) electrocatalyst that integrated alloying and heterostructuring strategies comprising FeCo alloy Mo0.82N (FeCo-Mo0.82N/NC). Notably, the maximum NH3 Faraday efficiency (FE) of 83.24%, yield 12.28 mg h-1 mgcat.-1, good stability were achieved over FeCo-Mo0.82N/NC. Moreover, Zn-NO3- battery assembled with FeCo-Mo0.82N/NC exhibited power density 0.87 mW cm-2, an 14.09 FE as high 76.31%.

Abstract Urea‐assisted water splitting is a promising energy‐saving hydrogen (H 2 ) production technology. However, its practical application hindered by the lack of high‐performance bifunctional catalysts for urea oxidation reaction (UOR) and evolution (HER). Herein, heterostructured catalyst comprising highly active NiSe Ni 3 Se , along with conductive graphene‐coated nickel foam skeleton (NiSe‐Ni /GNF) reported. The NiSe‐Ni originates from in situ selenization foam, allowing careful regulation to ratio simply adjusting calcination temperature. Theoretical calculations charge transfer between components can optimize pathways reduce corresponding energy barriers. Accordingly, designed exhibits excellent UOR HER activity stability. Furthermore, /GNF‐based UOR‐HER electrolyzer requires only 1.54 V achieve current density 50 mA cm −2 which lower than many recent reports much 1.83 OER‐HER electrolyzers. Moreover, exhibited negligible cell voltage variation during 28‐h stability test, indicating satisfactory stability, provides new viable paradigm H production.

Abstract Polylactic acid (PLA) composites with multifunctional properties and minimal filler content are increasingly in demand across various industries. However, achieving a balance between high mechanical strength, electrical conductivity, thermal electromagnetic interference (EMI) shielding remains challenging. In this study, dual‐processing strategy combining Pickering emulsion templating melt blending is presented to hybridize 1D carbon nanotubes (CNTs) 2D graphene nanoplatelets (GNPs) within PLA matrix. This approach successfully forms stable dual‐filler network, ensuring uniform dispersion of the fillers. The results show that method significantly enhances performance resulting PM‐PG x C y (P: emulsion; M: blending; y: mass fractions GNPs CNTs, respectively). Specifically, 1.43 composite exhibits remarkable improvements strength (56.2 MPa), conductivity (43.5 S m −1 ), EMI effectiveness (20.1 dB), (0.34 W m·K outperforming prepared using either alone. These findings indicate effectively combines fillers, facilitating superior interfacial interactions enhancing PLA‐based composites. study offers new high‐performance low content, offering significant potential for applications electronics, packaging, technologies.

Abstract Environmental‐friendly aqueous Zn−CO 2 batteries present bifunctional potentials of achieving carbon neutrality and energy storage. Nonetheless, anode corrosions derived from H O molecules high risks volatilization leakage hinder the advancement batteries. In this work, polyvinyl alcohol (PVA)‐based hydrogel electrolyte with fast ion diffusion kinetics, mechanical strength, flexibility is developed to replace liquid electrolyte. Since hydroxyl radicals in polymer chain can interact Zn 2+ , electrode corrosion free active around significantly inhibited, facilitating uniform deposition cations.

Plastics play a vital role in modern society, but their accumulation landfills and the environment presents significant risks to ecosystems human health. In addition, discarding of plastic waste constitutes loss valuable material. While usual mechanical recycling method often results reduced material quality, chemical offers exciting opportunities valorize into compounds interest. Its versatility leans on broad horizon reactions applicable, such as hydrogenolysis, hydrolysis, alcoholysis, or aminolysis. The development heterogeneous supported organocatalysts has enormous potential enhance economic industrial viability these technologies, reducing cost process mitigating its global environmental impact. This review summarizes challenges chemically heteroatom-containing plastics through catalysis, covering widely used polyesters (notably PET PLA), BPA-polycarbonate (BPA-PC), polyurethane (PU), polyamide (PA), polyether.

Polymer foams, particularly those prepared using supercritical carbon dioxide (Sc‐CO 2 ), are extensively utilized in diverse applications like thermal insulation and packaging due to their lightweight efficient properties. However, the effectiveness of Sc‐CO foaming is often limited by low cell density large size, mainly resulting from insufficient nucleation control inadequate gas management. In this study, hollow metal‐organic frameworks (MOFs) (HZIF‐8) were introduced as effective nucleating agents ‐assisted polystyrene (PS) foaming. Owing unique structure high internal surface area, HZIF‐8 significantly enhances adsorption storage capacity, thereby improving efficiency during process. The results show that incorporating into PS increases (up 1.4 × 10 9 cells cm −3 ) decreases average size (to 8.6 μm) under optimal conditions (13.8 MPa, 100 °C). Compared conventional ZIF‐8 nanoparticles, facilitates more CO uptake, leading a finer microcellular morphology, stable foam expansion, enhanced mechanical These demonstrate potential MOFs creating high‐performance with promising energy‐efficient insulation, packaging, functional materials.
