Abstract ：
Introducing advanced conductive nanoparticles to combine with metal-organic frameworks (MOFs) as electrode is emergingly regarded as a practical and efficient approach to improve the capacitive performance of super- capacitors. Herein, a new MOF (ZrNi-UiO-66, Nickel-zirconium 1,4-dicarboxybenzene) is designed to combine with carbon quantum dots (CQDs) to form a composite electrode with high specific capacitance, in which the charge regulation is performed to facilitate the electronic conduction and transfer. Such constructed electrode delivers an enhanced electronic conductivity and an improved specific capacitance of 2468.75 F g- 1 @ 1 A g- 1 , which is four times of the contrast sample. Meanwhile, the assembled hybrid supercapacitor exhibits an increased energy density and power density, as well as a sustainable stability after 10,000 cycles with a retention rate of 91.6 %. Basing on the study of advanced characterizations and density functional theory (DFT) simulation, the mechanism of significantly improved specific capacitance can be elaborated as the promote electronic conduction caused from narrowed band gap from 3.9 eV or 0.41 eV-0.23 eV, and the increased charge accumulation at the Ni sites in designed MOFs. This work provides new insights for the design and construction of potential energy storage materials based on MOFs and/or advanced carbon-based materials.

Abstract ：
High-temperature proton exchange membrane fuel cells (HT-PEMFCs) show broad application perspectives due to their faster reaction kinetics and tolerance to fuel/gas impurities as well as the easy water/heat managements. However, the catalysts and subsequent membrane electrode assemblies (MEAs) are still suffering from performance degradation, which severely restricts HT-PEMFCs' large-scale practical application. To overcome the challenges, developing high-performance catalysts and MEAs with advanced materials and optimized structures to achieve stable and efficient operation of HT-PEMFCs is necessary. To facilitate the research and development of HT-PEMFCs, a comprehensive overview of the latest developments in the design of active and stable catalysts and durable MEAs is presented in this paper. This review systematically summarizes the degradation mechanisms of catalysts, and corresponding mitigation strategies for improving the stability of catalysts and MEAs, aiming to effectively developing high-performance and durable HT-PEMFCs. Furthermore, the main challenges are analyzed and the future research directions for overcoming the challenges are also proposed for developing highactive and stable catalysts and MEAs used in HT-PEMFCs toward practical applications.

Abstract ：
MXenes, a unique class of 2D transition metal carbides, have gained attention for gas sensing applications due to their distinctive properties. Since the synthesis of Ti3C2Tx MXene in 2011, significant progress has been made in using MXenes as chemiresistive sensors. Their layered structure, abundant surface groups, hydrophilicity, tunable conductivity, and excellent thermal properties make MXenes ideal for low-power, flexible, room temperature gas sensors, fostering scalable and reproducible applications in portable devices. This review evaluates the latest advancements in MXene-based gas sensors, beginning with an overview of the elemental compositions, structures, and typical fabrication process of MXenes. We subsequently examine their applications in gas sensing domains, evaluating the proposed mechanisms for detecting common volatile organic compounds such as acetone, formaldehyde, ethanol, ammonia, and nitrogen oxides. To set this apart from similar reviews, our focus centered on the mechanistic interactions between MXene sensing materials and analytes (particularly for chemiresistive gas sensors), leveraging the distinct functionalities of MXene chemistries, which can be finely tuned for specific applications. Ultimately, we examine the current limitations and prospective research avenues concerning the utilization of MXenes in environmental and biomedical applications.

Abstract ：
The poor ambient ionic transport properties of poly(ethylene oxide) (PEO)-based SPEs can be greatly improved through filler introduction. Metal fluorides are effective in promoting the dissociation of lithium salts via the establishment of the Li-F bond. However, too strong Li-F interaction would impair the fast migration of lithium ions. Herein, magnesium aluminum fluoride (MAF) fillers are developed. Experimental and simulation results reveal that the Li-F bond strength could be readily altered by changing fluorine vacancy (VF) concentration in the MAF, and lithium salt anions can also be well immobilized, which realizes a balance between the dissociation degree of lithium salts and fast transport of lithium ions. Consequently, the Li symmetric cells cycle stably for more than 1400 h at 0.1 mA cm-2 with a LiF/Li3N-rich solid electrolyte interphase (SEI). The SPE exhibits a high ionic conductivity (0.5 mS cm-1) and large lithium-ion transference number (0.4), as well as high mechanical strength owing to the hydrogen bonding between MAF and PEO. The corresponding Li//LiFePO4 cells deliver a high discharge capacity of 160.1 mAh g-1 at 1 C and excellent cycling stability with 100.2 mAh g-1 retaining after 1000 cycles. The as-assembled pouch cells show excellent electrochemical stability even at rigorous conditions, demonstrating high safety and practicability. © 2024 American Chemical Society.

Abstract ：
Hydrogen energy serves as an ideal alternative energy carrier to fossil fuels in the future clean energy system. The hydrogen evolution reaction (HER) occurring at the cathode of water electrocatalysis has been considered as a promising approach to produce hydrogen over the past decades due to zero carbon emission. To gain a deep insight into the advanced electrocatalyst, herein, we provide a comprehensive review with an emphasis on the recent state-of-the-art advances of HER electrocatalysts in view of controlling their local electronic structure, creating defect nanostructures, exposing active sites, altering d band center, and constructing heterogeneous structure. Initially, we start with a brief introduction of the fundamental electrocatalytic mechanisms and the critical electrochemical parameters for evaluating HER. Then, we systemically discuss three representative classes of electrocatalysts, comprised of highly active noble-metal including single atom, nanoparticles, and clusters, earth-abundant transition metal such as transition metal sulfides, phosphides, carbides, nitrides, and oxides, and metal-free functional nanomaterials involving different dimensions of carbonaceous nanomaterials, boron nitrogen, and phosphorous non-carbonaceous nanomaterials by adjusting their tunable electronic structures and architectures/morphologies with a particular emphasis on the structure-function relationships. Finally, we point out the current challenges and opportunities in view of achieving highly active and stable electrocatalysts towards practical applications.

Abstract ：
Cellulose-based separator exhibits excellent electrolyte affinity, thermal stability, and mechanical strength, which acts as a promising alternative to commercial polyolefin separators in lithium metal batteries (LMBs). Fiber size in cellulose-based separators plays a crucial role in determining their physicochemical structure and mechanical strength, as well as the electrochemical performance of corresponding LMBs. Herein, the fiber size in cellulose-based separators was first time regulated to optimize their mechanical stability and the related battery performance. The influences of fiber size in the separator on chemical structure, mechanical properties, surface morphology, electrochemical behavior were investigated in detail, in which the underlying mechanism between separator structure and the related performance was elucidated. As a result, the separator optimized by fiber size regulation exhibited excellent thermal stability under 180 degrees C, good tensile strengths of 6.0 MPa and Young's moduli of 315.9 MPa, superior room temperature ionic conductivity of 1.87 mS cm-1, as well as significantly improved electrochemical performance of corresponding batteries. It can be concluded that structure optimization for cellulose-based separator through fiber size regulation is an effective and indispensable approach towards high safety and high performance LMBs.

Abstract ：
As one type of promising electrochemical technologies, high temperature proton exchange membrane fuel cells (HT-PEMFCs) have been widely recognized as the next-generation fuel cell technology for clean energy conversion due to their superiorities of fast electrochemical kinetics, simplified water management, good tolerance to feeding gas contaminants, low emission and high efficiency of energy conversion. However, performance failure during long-term operation still largely hinders their practical application. Accordingly, the explorations of advanced materials and structures, degradation mechanisms and mitigation strategies are attracting intensive attentions for promoting the progress of this technology. In addressing the timely update on the emerging progress regrading long-term durability of HT-PEMFCs, a comprehensive review summarizing the most recent developments of performance failure mechanisms and mitigation strategies for critical components of HT-PEMFCs is presented here. In this paper, the fundamentals involving basic reactions, main components, and development history are first summarized for fundamental understanding; then, the failure analysis and the corresponding mitigation strategies for critical components involving proton exchange membrane, catalytic layer, gas diffusion layer, bipolar plate, and thermal/water management systems are mainly emphasized. Furthermore, the technical challenges are analyzed and the further research directions are also proposed for overcoming the challenges toward practical application of HT-PEMFCs.

Abstract ：
Electrocatalytic oxidation as a promising route to produce value-added products from biomass-derived organics has received increasing attention in recent years. However, the efficient conversion of concentrated feedstock solutions with high selectivity and Faradaic efficiency (FE) remains challenging. Herein, we report a cation-defective Ni-based electrocatalyst derived from the surface reconstruction of the NiCo Prussian blue analogue (NiCo PBA) in alkaline media for the efficient oxidation of biomass-derived organics in a high concentration solution. Taking 5-hydroxymethylfurfural (HMF) as an example, the NiCo PBA can deliver a satisfactory catalytic performance in terms of high HMF conversion (97%), selectivity to 2,5-furandicarboxylic acid (98%), and FE (100%), even at a concentration as high as 100 mM. Theoretical calculations suggest that the cation defects not only promote the fast conversion of Ni(OH)(2) to electrochemically active NiOOH under anodic potential but also enhance the adsorption of HMF onto the active sites and accelerate the spontaneous chemical oxidation. This study provides deep insights into the structural evolution of PBA-based catalysts and reveals the pivotal factor that affects the performance of electrocatalytic oxidation, paving the way to further develop advanced electrocatalysts for efficient oxidation reactions with a high concentration.

Lithium metal batteries (LMBs) are considered as one type of the most promising next-generation energy storage devices with high-energy-density, and stabilizing the lithium metal anodes (LMAs) to overcome LMBs' safety concerns and performance degradation has attracted extensive attention. Introducing advanced polymer materials into the critical components of LMBs has proven to be an effective and promising approach for stabilizing LMAs toward practical application of LMBs. In addressing the lack of a timely review on the emerging progress of advanced polymer materials in LMBs for stabilizing LMAs, a comprehensive article summarizing the most recent developments of multiscale cellulose materials, including micron cellulose (MC) and nanocellulose (NC), in LMBs is reviewed. First, the basic structures of cellulose, characteristics comparison, and the development history of introducing cellulose into LMBs are presented. Furthermore, the roles of multiscale cellulose materials and functional mechanisms in various components of LMBs for stabilizing LMAs are summarized. A general conclusion and a perspective on the current limitations and future research directions of cellulose-based stable LMBs are proposed. The aim of this review is not only to summarize the recent progress of multiscale cellulose materials in stabilizing LMAs but also to lighten the pathways for realizing LMBs' practical application. This review aims to provide an in-depth summary of the roles of multiscale cellulose materials (i.e., micron cellulose (MC) and nanocellulose (NC)) in various components of lithium-metal batteries (LMBs), including separators, electrolytes, interfaces, and anode current collectors. Additionally, a general conclusion and a perspective on the current limitations and future research directions of cellulose-based stable LMBs are proposed. image
