However, eNRR remains significantly hindered by the extreme stability of the N≡N bond, slow proton-coupled electron transfer (PCET), and the kinetically favored hydrogen evolution reaction (HER), which collectively reduce ammonia yield and Faradaic efficiency. MXenes represent a unique class of 2D transition-metal carbides, nitrides, and carbonitrides, distinguished by chemically versatile transition-metal active sites, defect-rich structures, tunable surface terminations, and metallic conductivity. These properties enable unprecedented tuning of N2 adsorption, interfacial charge redistribution, orbital hybridization, and adsorption energetics, enabling selective N2 activation while minimizing competing proton reduction. This review provides a critical overview of the design principles of MXene-based electrocatalysts for selective ammonia synthesis. The distinctive contribution of this review is to systematically link MXene composition, vacancy engineering, heteroatom doping, single-atom anchoring, and assembling MXene heterostructures to their effects on electronic structure, adsorption free-energy landscapes, NRR pathways, and HER suppression. Particular emphasis is placed on understanding catalytic selectivity in terms of the underlying mechanism and structure–activity relationships, derived through advanced operando characterization, density functional theory, and emerging machine-learning-assisted catalyst discovery.","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 6","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70210","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This Review provides a critical overview of recent advances in MXene-based anodes for PIBs, with emphasis on interlayer spacing expansion, surface termination regulation, and heterostructure design. It also examines the underlying potassium-storage mechanisms, including intercalation, pseudocapacitive storage, conversion reactions, and alloying-related processes. The discussion examines how interfacial charge transfer, defect engineering, and the “trapping-conversion” mechanism contribute to improved electrochemical performance. Finally, this review discusses key challenges associated with MXene-based PIB anodes, including interfacial instability, full-cell compatibility, and performance verification under practical operating conditions.

In this study, a CuNiCoFeMn@KB high-entropy alloy (HEA) catalyst was successfully synthesized via a one-pot solvothermal reduction strategy. Structural and theoretical analyses suggest that the multi-element alloying and high-entropy-like configuration alter the local surface composition and synergistically modulate the electronic structure, inducing an upshift of the d-band center, which significantly enhances the adsorption of key reaction intermediates. Electrochemical evaluations demonstrated that the catalyst achieves a Faradaic efficiency of 57.3% for ethanol at −0.75 V versus RHE, with a current density of 32.83 mA cm−2 at −0.95 V, while maintaining robust long-term stability exceeding 120 h. The regulatory mechanism of configurational entropy on CO2RR pathways was systematically investigated through a combination of density functional theory (DFT) calculations and experimental validation. Theoretical results indicate that *OCCO serves as the pivotal intermediate in the ethanol formation pathway. An increase in ΔSconf improves the thermodynamic preference for *OCCO dimerization, conferring a thermodynamic advantage for C─C coupling. This provides a potential “entropy regulation-adsorption energy-reaction pathway” correlation model.

Here, a kinetic-coordinated mechano-electrochemical steady-state architecture is proposed for LixSi–Se ASSLBs. It dynamically counterbalances the Se cathode volumetric expansion with the continuous contraction of the LixSi anode during cycling. The conversion kinetics of Se promote temporal coordination with the anode, thereby mitigating transient mechanical imbalance. This volumetric and kinetic dual-matching results in a pressure change of −0.137 MPa at the discharge–charge transition in the 20th cycle. Its absolute magnitude is more than one order of magnitude lower than that of the Li–Se cell (−2.721 MPa). The mechanically stabilized interfaces suppress long-range cracking and help maintain continuous solid–solid contact. Consequently, the LixSi–Se system delivers excellent specific capacities of 579.1, 510.4, 369.4, 260.1, and 170.5 mAh g−1 at 0.1, 0.2, 0.5, 1, and 2C, respectively. More importantly, scaled-up 10 × 10 cm2 pouch cells achieve a high reversible capacity of 1.13 Ah. Their peak capacity of 1.16 Ah corresponds to a calculated gravimetric energy density of 274.15 Wh kg−1 based on the combined masses of the cathode, solid-state electrolyte, and anode. This work establishes this dual-matching paradigm as a general design principle for overcoming interfacial mechanical failures in high-energy ASSLBs.","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 6","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70206","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149072595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a scalable molten-salt–assisted strategy is developed to construct 2D in-plane heterostructured Mo2C/MoN nanosheets with tunable interfaces, which involves carbonization of bulk MoO3 into Mo2C nanosheets in molten salt, followed by partial topochemical nitridation to convert Mo2C into MoN. Electrochemical quartz crystal microbalance and in situ Raman spectroscopy reveal that the pseudocapacitance arises primarily from reversible H+ interactions with Mo–C sites in Mo2C, with additional contribution from Mo–N sites. Ultraviolet photoelectron spectroscopy and density functional theory calculations confirm that the interfacial electron transfer from Mo2C to MoN upshifts the d-band center of Mo2C and reduces its H+ adsorption energy from −0.522 to −1.526 eV; meanwhile, electron injection into MoN weakens the Mo–N coordination and creates undercoordinated Mo sites. These two effects synergistically promote the pseudocapacitive redox activity. The optimized Mo2C/MoN achieves a large capacitance of 323.6 F g−1 (899.6 F cm−3) at 1 A g−1, high rate capability (204.7 F g−1 at 10 A g−1), and 91.1% capacitance retention after 10,000 cycles in 1 M H2SO4.

It was demonstrated that gradient structures with controllable graded physicochemical properties overcome the limitations of conventional homogeneous structures in simultaneously achieving rapid kinetics and interfacial stability. Herein, this review summarizes different gradient structures and emphasizes their key roles in elevating ion kinetics. First, it was revealed that, in the absence of gradient structures, the interfaces exhibited sluggish transport kinetics due to a single electrolyte concentration profile, spontaneously formed a random SEI, and featured defects with highly concentrated nucleation sites. Second, to elucidate the evolution of gradient structures at interfaces, monitoring methods for dynamic gradients were established from both temporal and spatial dimensions. More fundamentally, it was revealed that the core design principles by which gradient structures enhance kinetics lie in achieving directional regulation of Li ions tailored to the distinct intrinsic characteristics of different interfaces. Specifically, the solvation-gradient structures accelerated desolvation in the electrolyte; the SEI-gradient structures stabilized rapid lithium-ion transport at the liquid–solid interface; and the host-parameter-gradient structures promoted uniform nucleation and deposition at the solid interface.","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 5","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148994059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
