Highlights
By introducing fluorine modulation into MXene, a new MXene-derived material TiOF/Ti3C2 was successfully synthesized with a distinctive three-dimensional structure and a tailored F distribution.
In situ characterizations and electrochemical analyses demonstrate that TiOF/Ti3C2 catalysts effectively coupled the multiphase sulfur species conversion processes.
The investigations reveal that the theoretical basis of the fluorine catalysis in Li–S batteries originated from Lewis acid–base mechanisms and charge compensation mechanisms.
氟因其固有的高电负性而具有电荷析出和离子解离能力；因此，大量研究集中于利用氟化物优化固体电解质界面，并为电极提供动态保护，以调节电池的反应和功能性能。然而，穿梭效应和缓慢的氧化还原反应动力学强调了锂硫电池的潜在瓶颈。氟调制是否能调节锂硫化学反应过程？在此，我们通过 NH4F 氟化法构建了具有定制 F 分布的 TiOF/Ti3C2 MXene 纳米带。根据原位表征和电化学分析，F 激活了 Ti 金属原子在连续氧化还原反应中的催化作用。基于路易斯酸碱机制形成的 O-Ti-F 键增加了 Ti 金属位点的正电荷，这有助于吸附多硫化物，提供更多的成核位点，并促进 S-S 键的裂解。这有助于在较低的过电位下沉积 Li2S。此外，由于电荷补偿机制，氟还能捕获 Li2S 溶解产生的电子。氟调制策略有望指导氟基催化剂的构建，并促进多个连续异相催化过程的无缝集成。

Single-ion conductors based on covalent organic frameworks (COFs) have garnered attention as a potential alternative to currently prevalent inorganic ion conductors owing to their structural uniqueness and chemical versatility. However, the sluggish Li+ conduction has hindered their practical applications. Here, we present a class of solvent-free COF single-ion conductors (Li-COF@P) based on weak ion–dipole interaction as opposed to traditional strong ion–ion interaction. The ion (Li+ from the COF)–dipole (oxygen from poly(ethylene glycol) diacrylate embedded in the COF pores) interaction in the Li-COF@P promotes ion dissociation and Li+ migration via directional ionic channels. Driven by this single-ion transport behavior, the Li-COF@P enables reversible Li plating/stripping on Li-metal electrodes and stable cycling performance (88.3% after 2000 cycles) in organic batteries (Li metal anode||5,5’-dimethyl-2,2’-bis-p-benzoquinone (Me2BBQ) cathode) under ambient operating conditions, highlighting the electrochemical viability of the Li-COF@P for all-solid-state organic batteries.

Highlights
Developing surface-functionalized catalysts with exceptional activity and selectivity for the electrocatalytic CO2RR to C2+ products under neutral electrolyte.
A remarkable C2+ FE of nearly 90% at an unprecedented current density of 300 mA cm−2 and maintain high FE (> 80%) at the wide current density performance (100–600 mA cm−2) in neutral environments using a flow cell as well as MEA electrolyzer.
Mechanical study reveals that reducing the coverage of coordinated K·H2O water increased the probability of intermediate reactants (CO) interacting with the surface, thereby promoting efficient C–C coupling and enhancing the yield of C2+ products.
铜基催化剂的表面功能化主要通过抑制寄生氢演化反应和促进电极上 CO2/CO 的局部浓缩，在增强电化学 CO2 还原反应 (CO2RR) 以生成多碳 (C2+) 产物方面具有广阔的潜力。基于这种方法，我们开发出了表面功能化催化剂，具有优异的活性和选择性，可在中性电解质中电催化 CO2RR 到 C2+。利用涂有六乙炔苯有机分子的 CuO 纳米粒子（HEB-CuO NPs），在 300 mA cm-2 的空前电流密度下，C2+ 法拉第效率达到了近 90% 的显著水平，而且在中性环境下使用流动池，在宽电流密度范围（100-600 mA cm-2）内都能保持较高的 FE（> 80%）。此外，在膜电极组件（MEA）电解槽中，部分电流密度为 387.6 mA cm-2 时，FEC2+ 的浓度达到了 86.14%，同时在电流密度为 200 mA cm-2 时，该电解槽可连续运行 50 小时以上。原位光谱研究和分子动力学模拟显示，降低配位 K⋅H2O 水的覆盖率可增加中间反应物（CO）与表面相互作用的概率，从而促进高效的 C-C 偶联并提高 C2+ 产物的产量。这一进展为优化局部微环境以实现可持续和高效的 C2+ 生产提供了巨大的潜力。

Li-rich layered oxide (LRLO) cathodes have been regarded as promising candidates for next-generation Li-ion batteries due to their exceptionally high energy density, which combines cationic and anionic redox activities. However, continuous voltage decay during cycling remains the primary obstacle for practical applications, which has yet to be fundamentally addressed. It is widely acknowledged that voltage decay originates from the irreversible migration of transition metal ions, which usually further exacerbates structural evolution and aggravates the irreversible oxygen redox reactions. Recently, constructing O2-type structure has been considered one of the most promising approaches for inhibiting voltage decay. In this review, the relationship between voltage decay and structural evolution is systematically elucidated. Strategies to suppress voltage decay are systematically summarized. Additionally, the design of O2-type structure and the corresponding mechanism of suppressing voltage decay are comprehensively discussed. Unfortunately, the reported O2-type LRLO cathodes still exhibit partially disordered structure with extended cycles. Herein, the factors that may cause the irreversible transition metal migrations in O2-type LRLO materials are also explored, while the perspectives and challenges for designing high-performance O2-type LRLO cathodes without voltage decay are proposed.
