The structural diversity and sustainability of organic electrode materials make them highly appealing for symmetric all-organic batteries (SAOBs). However, achieving high-performance organic materials with a synergistic effect that involves abundant active centers, strong intermolecular interactions, and a high affinity for sodium ions remains challenging. Herein, we report the development of porous poly(imine-anthraquinone) nanorods (PIAN). The PIAN framework contains abundant C═O and C═N functional groups with distinct redox plateaus, which both serve as cathodic and anodic active centers, respectively, ensuring a high capacity and potential in SAOBs. The conjugated PIAN exhibits a high reversible capacity of 393 mA h g-1 and stable long-term cycling performance (retaining 90 mA h g-1 after 5,000 cycles at 10 A g-1), as confirmed by in situ and ex situ measurements. Furthermore, density functional theory (DFT) calculations reveal that the PIAN electrode possesses rapid Na+ ion diffusion kinetics and follows a two-step multisodium ion storage mechanism. The PIAN-based SAOBs achieve a high capacity of 178 mA h g-1 and retain 79.6% of their initial capacity at 1 A g-1 after 500 cycles. This work introduces a redox-active polymeric electrode material and is expected to inspire further research on organic materials with superior electrochemical performance for practical applications. © 2025 American Chemical Society.

Here, bacterial cellulose (BC) intercalated Ti3C2Tx (BCT) fiber was fabricated by wet spinning method for fiber shaped supercapacitors (FSC). BC can significantly impede the self-restacking of Ti3C2Tx flakes causing a porous structure and connect the adjacent Ti3C2Tx sheets constructing high mechanical strength. As a result, the BCT fiber provides high capacitance and good rate performance in three-electrode system. Moreover, the assembled symmetrical FSC based on BCT fiber presents favorable mass capacitance and excellent energy density, demonstrating a bright future in smart wearable system. © 2025 Elsevier B.V.

Metallic residues in biomass-derived hard carbons (HCs) are conventionally considered detrimental to Na+ ions storage, recent breakthroughs reveal that controlled metal-ion doping can substantially enhance electrochemical performance. Suitable metal doping is beneficial to enhance its overall performance. Consequently, manipulating the microstructure of HCs at the molecular level to achieve adaptive doping with metal ions, thereby fostering smoother diffusion environments and increasing storage sites for Na+ ions, is crucial for achieving exceptional sodium-ion batteries (SIBs) performance. This review delves into the commercialization potential of SIBs and provides a comprehensive summary of the development trajectory of metal ion-catalyzed hydrocarbons (MICHCs), which encompasses synthesis methodologies, the intricate relationship between metal doping position/content and performance, underlying reaction mechanisms. Regarding the catalytic mechanism of metal ions, this review outlines the interaction between metal ions and HCs, offering theoretical foundations and practical guidance for developing high-performance sodium storage materials. By regulating the content and type of metal ions, one can adjust the physicochemical properties of the local microstructure and improve the electrochemical properties of MICHCs. Research on MICHCs not only advances related disciplines but also fosters technological innovation and industrial upgrading. This review discusses the future developments and challenges facing key technologies in this burgeoning field. © 2025 Wiley-VCH GmbH.

Wastewater is a potential resource warehouse, and converting wastewater into treasures is significant in addressing the environmental and energy crisis. The solar-driven photoelectrocatalytic (PEC) process is considered a promising technology because it can utilize solar light for driving chemical conversion. However, previous studies on the PEC process have mainly focused on wastewater purification and water splitting, overlooking its potential for chemicals (fine products, ammonia, hydrogen peroxide, and metal resources) extraction and energy (hydrogen and electricity) recovery. Thus, a review of in-depth understanding and state-of-the-art account on multifunctional PEC-coupled processes that aim to integrate wastewater treatment and resource conversion is desired. This review offers an overview of PEC-coupled processes for the recovery of valuable resources from wastewater. First, several typical wastewaters are pointed out and their potential for resource utilization is assessed separately. Next, the wastewater treatment mechanism and the recovery model of valuable resources in the PEC wastewater treatment system are recalled. Then, the recent progress is comprehensively overviewed and discussed in the PEC conversion of various wastewaters into high-value chemicals and energy. Finally, the main challenges and future perspectives for PEC wastewater resourcing are presented. This review points the path for PEC technology to address the solar-wastewater-energy nexus and offers evolutionary opportunities for future generations of waste-to-chemicals/energy conversion processes. © 2025 Elsevier B.V.

Solar-driven water purification is recognized as an effective and sustainable technology for tackling the global water crisis by utilizing clean and renewable solar energy. In this study, we present a mussel-inspired MXene-functionalized sponge (denoted as POPM sponge), which features a 3D interconnected porous structure, enhanced surface hydrophobicity, and efficient photothermal conversion capabilities. The design and fabrication of the POPM sponge involve integrating mussel-inspired hydrophobic Ti3C2Tx MXene nanosheets with a 3D interconnected porous PDMS sponge as precursors. This POPM sponge shows considerable potential as a multifunctional photothermal material to promote solar-driven water purification in complex wastewater systems. With its superior surface hydrophobicity and high photothermal conversion efficiency, this POPM sponge effectively recovers high-viscosity crude oil spills through photothermal-driven absorption. Moreover, it functions as an efficient solar evaporator, exhibiting high water evaporation rates and remarkable photothermal conversion efficiencies, thereby facilitating cost-effective solar-driven water purification in complex wastewater systems. Additionally, it possesses remarkable photothermal antibacterial characteristics for the sterilization of common pathogenic bacteria in wastewater, indicating its potential as a promising photothermal material for sterilization applications in such environments. This strategy offers a pathway for the development of multifunctional photothermal materials aimed at enhancing the efficiency of solar-driven water purification in complex wastewater systems within practical applications. © 2025 Elsevier B.V.

Defect engineering is an essential technique for controlling the characteristics of carbon nanomaterials. Introducing heteroatom (N&S) dopants and vacancies into the C[sbnd]C bond (sp2) framework could exemplify several advantages. Advantages include increased active sites, modification of surface charge transfer properties, and enhancement of electrochemical performance. Herein, an innovative approach is proposed to generate carbon spheres from lignocellulosic material extracted from the Artocarpus heterophyllus peel waste. Preferentially, L-cysteine (1 %) amino acid was chosen as a favorable source of heteroatoms because of the highly reactive carbocation (C2 position) promoting defects on the negatively charged carbon spheres. Moreover, 1 % L-cysteine integrated carbon spheres (LCCS−1) were subjected to physicochemical characterization to analyze their structural and morphological properties, specific surface area, porosity, elemental composition, and atomic percentage (%). LCCS−1 coated electrode in 3 M KOH electrolyte displayed a capacitance and diffusion contribution of 82.8 % and 17.2 %, as evident from Trasatti and Dunn's plot. Remarkably, the fabricated LCCS-1//LCCS-1 symmetric supercapacitor device (SSD) demonstrated a specific capacitance of 177 F g−1 at 1 A g−1 current density in a PVA: KOH gel electrolyte medium. Subsequently, LCCS-1//LCCS-1 SSD achieved a phenomenal operating voltage range of 0–2.0 V with a calculated energy density of 36.1 Wh/kg and 10,000 W/kg power density. Concordantly, the connected LCCS-1//LCCS-1 device effectively illuminated red colour LED light, achieving a superior efficacy of ∼112 %. The outstanding electrochemical characteristics of LCCS-1 serve as a source of inspiration for the logical development of defect-modulated electrode materials with enhanced performance in energy storage applications. © 2025 Elsevier B.V.

Journal of Environmental Chemical engineering 2025年第3期13卷

作者： Heng Wang Zhe Yu Yongjie Sun Jiahao Zhou Yuxuan Yang Yiming Yang Xiufang Chen Fengtao Chen Wangyang Lu National Engineering Lab for Textile Fiber Materials & Processing Technology (Zhejiang) Zhejiang Sci-Tech University Hangzhou 310018 China

To enhance perovskite type catalysts with catalytic ozonation performance, a noval porous perovskite La 0.9 Ce 0.1 CoO 3 was facilely developed by soft-templating method and subsequently evaluated in a heterogeneous catalytic ozonation system. Polyvinylpyrrolidone-modified La 0.9 Ce 0.1 CoO 3 (PVP-La 0.9 Ce 0.1 CoO 3 ) exhibited the remarkable catalytic performance, achieving a total organic carbon (TOC) removal rate of nitrobenzene as high as 93.9 % within 25 min. The enhanced catalytic efficiency may be primarily due to the increased surface area and porous structure. Radical quenching experiments and electron paramagnetic resonance (EPR) spin trapping experiments were conducted to identify the primary reactive species, revealing that hydroxyl radicals (•OH) played a pivotal role in the nitrobenzene mineralization process. A possible catalytic degradation pathway was proposed through detecting and analyzing the reaction intermediates of catalytic degradation process using gas chromatography-mass spectrometry (GC-MS). This research presents a novel approach for fabricating porous perovskite-type catalysts with a higher specific surface area (SSA) and enhanced ozone catalytic activity.
