To achieve this objective, a template-oriented strategy coupled with multi-heteroatom modification is proposed to precisely synthesize a three-dimensional boron/nitrogen-rich carbon nanoflake-interconnected micro/nano superstructure, referred to as BNPC. The hierarchically porous framework of BNPC shares short channels for fast Zn2+ transport, increased adsorption-site accessibility, and structural robustness. Additionally, the boron/nitrogen incorporation effect significantly augments Zn2+ adsorption capability and more distinctive pseudocapacitive nature, notably enhancing Zn-ion storage and transmission kinetics by performing the dual-storage mechanism of the electric double-layer capacitance and Faradaic redox process in BNPC cathode. These merits contribute to a high capacity (143.7 mAh g−1 at 0.2 A g−1) and excellent rate capability (84.5 mAh g−1 at 30 A g−1) of BNPC-based aqueous ZHC, and the ZHC still shows an ultrahigh capacity of 108.5 mAh g−1 even under a high BNPC mass loading of 12 mg cm−2. More critically, the BNPC-based flexible device also sustains notable cyclability over 30,000 cycles and low-rate self-discharge of 2.13 mV h−1 along with a preeminent energy output of 117.15 Wh kg−1 at a power density of 163.15 W kg−1, favoring a creditable applicability in modern electronics. In/ex-situ analysis and theoretical calculations elaborately elucidate the enhanced charge storage mechanism in depth. The findings offer a promising platform for the development of advanced carbon cathodes and corresponding electrochemical devices.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 3","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.673","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photoinduced electron transfer reversible addition–fragmentation chain-transfer (PET-RAFT) polymerization is a precise methodology for constructing polymers with well-defined structures. However, conventional semiconductor-mediated PET-RAFT polymerization still has considerable limitations in terms of efficiency as well as the polymerization environment. Herein, sulfur-doped carbonized polymer dots (CPDs) were hydrothermally synthesized for catalysis of aqueous PET-RAFT polymerization at unprecedented efficiency with a highest propagation rate of 5.05 h−1. The resulting polymers have well-controlled molecular weight and narrow molecular weight dispersion (Ð < 1.10). Based on the optoelectronic characterizations, we obtained insights into the photoinduced electron transfer process and proposed the mechanism for CPD-mediated PET-RAFT polymerization. In addition, as-synthesized CPDs for PET-RAFT polymerization were also demonstrated to be suitable for a wide range of light sources (blue/green/solar irradiation), numerous monomers, low catalyst loading (low as 0.01 mg mL−1), and multiple polar solvent environments, all of which allowed to achieve efficiencies much higher than those of existing semiconductor-mediated methods. Finally, the CPDs were confirmed to be non-cytotoxic and catalyzed PET-RAFT polymerization successfully in cell culture media, indicating broad prospects in biomedical fields.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 3","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.686","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although an interface modification strategy has been applied to optimize the stability of Zn metal anodes and has shown some improvement, they are still far from meeting the requirements for practical applications. There is a lack of consideration for designing a multifunctional solid electrolyte interphase (SEI) which modifies the solvation/desolvation structure of Zn ion at the interface of Zn metal anodes. Herein, we constructed an amphiphilic SEI with hydrophilic and hydrophobic properties: N, S dual-doped graphene quantum dots (GQDs). The N, S dual-doped GQDs have been synthesized using a one-step hydrothermal approach and were utilized for Zn anode surface modification. When regulating the solvation structure of the Zn ion interface by N, S dual-doped GQDs, it also promotes its desolvation kinetics, optimizes the interfacial behavior of Zn ion deposition to prohibit Zn dendrite growth, and suppresses side reactions in the Zn anode surface. The Zn|Zn symmetric cell has achieved a long cycle life of more than 800 h at 5 mA cm−2. The Zn|V2O5 battery has achieved an excellent performance of more than 80% capacity retention after 1400 cycles at 1 A g−1.

However, its energy efficiency is significantly constrained by the kinetically slow oxygen evolution reaction (OER) at the anode, which accounts for about 90% of the electrical energy consumption in the water-splitting process. A new strategy is urgently needed to reduce its energy consumption. In recent years, electrochemical oxidation of small molecules has been considered for replacement of OER for efficient H2 production, due to its benign operational conditions, low theoretical thermodynamic potential, high conversion efficiency and selectivity, and environmental sustainability. Hybrid electrolysis systems, by integrating cathodic hydrogen evolution reaction with anodic oxidation of small molecules, have been introduced, which can generate high-purity H2 and produce value-added products or pollutant degradation. In this review, we highlight the recent advancements and significant milestones achieved in hybrid water electrolysis systems. The focus is on non-noble metal electrocatalysts, reaction mechanisms, and the construction of electrolyzers.

Due to the high specific surface area and one-dimensional long-range continuous structure of the nanofiber, ion-charged groups can be induced to form long-range continuous ion transfer channels in the nanofiber composite membrane, significantly increasing the ion conductivity of the membrane. This review stands apart from previous endeavors by offering a comprehensive overview of the strategies employed over the past decade in utilizing both electrospun and natural nanofibers as key components of proton exchange membranes and anion exchange membranes for fuel cells. Electrospun nanofibers are categorized based on their material properties into two primary groups: (1) ionomer nanofibers, inherently endowed with the ability to conduct H+ (such as perfluorosulfonic acid or sulfonated poly(ether ether ketone)) or OH− (e.g., FAA-3), and (2) nonionic polymer nanofibers, comprising inert polymers like polyvinylidene difluoride, polytetrafluoroethylene, and polyacrylonitrile. Notably, the latter often necessitates surface modifications to impart ion transport channels, given their inherent proton inertness. Furthermore, this review delves into the recent progress made with three natural nanofibers derived from biodegradable cellulose—cellulose nanocrystals, cellulose nanofibers, and bacterial nanofibers—as crucial elements in polyelectrolyte membranes. The effect of the physical structure of such nanofibers on polyelectrolyte membrane properties is also briefly discussed. Lastly, the review emphasizes the challenges and outlines potential solutions for future research in the field of nanofiber-based polyelectrolyte membranes, aiming to propel the development of high-performance polymer electrolyte fuel cells.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 4","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.677","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3D matrices with radial direction nitrogen-doped carbon nanotube clusters achieve ultrahigh surface area, photothermal efficiency, and hydrophilicity, which significantly intensifies the whole interfacial solar evaporation process. The new solar evaporation efficiency reaches as high as 96.8%. Furthermore, our ab initio molecular dynamics simulation reveals that N-doped carbon nanotubes exhibit a greater number of electronic states in close proximity to the Fermi level when compared to pristine carbon nanotubes.
