Aerogels are of a popular choice for oil-water separation and water purification due to their attractive properties, such as lightweight, large surface area, and high porosity. Developing robust aerogels with multifunctional characteristics is highly desirable but remains challenging nowadays. Herein, we develop a facile one-pot condensation strategy for the fabrication of superhydrophilic-oleophobic (SHI-OP) composite aerogels using cellulose nanofibers (CNF), 3-glycidy-loxypropyl trimethoxysilane (GPTMS), polyethyleneimine (PEI) and fluorine-contained compound (FS-60). The resulted aerogels exhibit a directional lamellar structure with interconnected macropores, super-lightweight with high porosity of 98.30% and low density of 0.0256 ***-3. Also, the aerogels are mechanically durable against repeated compression. Meanwhile, the amphibious SHI-OP feature of the composite aerogels in both air and water states enables them to not only absorb trace amount of water from contaminated oils, but also separate oil-water mixtures with separation efficiency of over 99% and high permeation flux of over 9060 L/m2·h. Moreover, the aerogels also show excellent dye adsorption capability and reusability toward anionic dyes with a maximum adsorption capacity of 1245.68 mg/g. Such robust and multifunctional aerogels with special surface wettability provide good opportunity for liquid purification and dye-containing wastewater treatment. © 2023, The Authors.

Strengthening the operational durability of oxygen reduction reaction (ORR) catalysts is essential for advancing both fuel cells and metal–air batteries. However, developing highly active and durable catalysts remains a significant challenge. In this study, a catalyst (Co/Cu–N–C) featuring uniformly distributed Co nanoparticles (NPs) and Co/Cu sites has been synthesized via a facile complexassisted pyrolysis strategy. We observed that Cu–N–C support effectively confines the growth and leaching of Co NPs during both synthesis and ORR catalysis, thereby boosting the stability of the catalyst. Meanwhile, the presence of Co NPs and Cu sites slightly contributes to the ORR activity by optimizing the *OH desorption. The assembled zinc–air battery (ZAB) demonstrates a superhigh power density of 256.1 mW·cm−2 and a long-term operational stability exceeding 500 h. This work not only underscores the potential of bimetallic systems and NPs in enhancing catalyst stability but also provides valuable insights for the synthesis of high-performance ORR electrocatalysts. © The Author(s) 2025.

Two-dimensional materials for enhanced mid-infrared thermal management

Thermal management in the mid-infrared (MIR) range is gaining critical importance across diverse applications, such as in energy-efficient architecture and sophisticated electronic thermal regulation. However, traditional materials are often constrained by insufficient thermal conductivity, limited spectral flexibility, and susceptibility to degradation under extreme conditions, all of which undermine their effectiveness in the MIR domain. Although two-dimensional (2D) materials, including graphene, hexagonal boron nitride (h-BN), and transition metal carbides/nitrides (MXenes), have garnered considerable attention for addressing these limitations, a thorough understanding of their structural advantages specific to MIR thermal management remains scarce. This review seeks to bridge this gap by offering a detailed structural analysis of these 2D materials within the context of MIR applications. Initially, the inherent structural features of graphene, h-BN, and MXenes are examined, illustrating how these enable advanced MIR functionalities, such as efficient radiative heating, cooling, and dynamic modulation. Subsequently, an in-depth evaluation of their performance across various application areas is provided, including thermal radiation control and spectral regulation, with insights into their domain-specific advantages. Finally, also explores the challenges and proposes future directions, highlighting structural design strategies aimed at enhancing their applicability in MIR thermal management. This review not only underscores the unique potential of 2D materials but also provides a strategic framework to inform future research and innovation in MIR thermal management technologies. © 2025 IOP Publishing Ltd.

The uncontrollable growth of lithium dendrites and low columbic efficiency in liquid electrolytes seriously impede the development of high-performance lithium-metal batteries. The emerging approach of in-situ polymerization of solid polymer electrolytes (SPEs) based on 1,3-dioxolane (DOL) provides a new method of solving the high interfacial impedance and unstable long cycling performance of Lithium metal battery. Until now, the role of Lewis acid catalysts on the DOL polymerization has only been limited as the catalyst, nevertheless their alloying ability with Li metal has been ignored, which is important to the formation of artificial SEI as additives. Here, InF3 catalyst was adopted to simultaneously initiate the polymerization of DOL and construct a LiF/LixIn based composite SEI layer through its reaction with Li metal. Electrochemical measurement results show that its oxidation potential is up to 4.5V and the Li+ transference number is 0.39. Compared with SnF2 catalyst and commercial electrolyte, PDOL with InF3 catalyst show lower interfacial resistances, much uniform lithium deposition and higher Li plating/striping efficiencies. After 500 cycles at 0.5C, the assembled Li/LiFePO4 solid battery delivers a 118mAh/g and 75% capacity retention, with high average Coulombic efficiency of 99.9%. This innovative and facile strategy of dual functional InF3 on the in-situ polymerization of DOL and SEI formation provides new ideas for design solid polymer electrolytes. © 2023, The Authors.

Space-confined catalysis of iodine with oxygen vacancy-driven nanopump for durable aqueous zinc-iodine batteries

Aqueous zinc-iodine (Zn-I 2 ) batteries represent a promising solution for long-duration energy storage; however, the challenge of polyiodide shuttling remains a critical limitation. To address this issue, we engineered an oxygen vacancy-driven nanopump for I 2 molecules based on a two-dimensional van der Waals heterostructure, comprising oxygen vacancy-rich Ti-Nb bimetallic oxide nanosheets sandwiched between carbon layers (V o -TNO@C). The oxygen vacancies in V o -TNO@C strongly interact with I 2 , facilitating effective capture and confinement of I 2 within the interlayer gap. The confined I 2 is catalytically transformed in situ by the oxygen vacancies, altering the reaction pathway from the conventional approach (I 2 → I 3 − → I − ) to a more efficient way (I 2 → I − ). This confined catalysis significantly accelerates conversion kinetics and suppresses polyiodide formation, resulting in shuttle-free Zn-I 2 batteries with an exceptional lifespan exceeding 70,000 cycles.

Lead-free halide perovskites have excellent optoelectronic properties and have been widely studied in the optoelectronic field. A kind of all-inorganic double perovskite crystals (PCs) with high output voltage and high sensitivity was successfully synthesized via a more energy-efficient crystallization method in this study. The luminescence intensity of the perovskite crystals was significantly enhanced by Bi3+ doping. These perovskite crystals were used to prepare red light-emitting diodes (LEDs) with color purity of up to 93.1 %. In addition, the perovskite crystals were used to modify aramid chopped fibers (ACFs)/polyphenylene sulfide (PPS) composite fibers to fabricate flexible luminescent fibers. The modified composite fibers also demonstrated exceptional piezoelectric properties. Therefore, the modified composite fiber was used to prepare a piezoelectric sensor. The maximum output voltage of the sensor could reach 50 V at room temperature with a response time of only 8 ms. The piezoelectric constant d33 of this piezoelectric sensor was 374 pC/N, indicating that the sensor had high sensitivity. When the temperature increased to 373 K, the output voltage gradually rose to 100 V. The red and white LED devices demonstrated the potential of perovskites for lighting and display applications. Meanwhile, the flexible light-emitting fibers and piezoelectric sensors further expanded the application scope of perovskite in multifunctional optoelectronic devices. © 2025 Elsevier B.V.
