Single atom catalyst (SAC) show significant promise in electrocatalytic carbon dioxide reduction reaction (eCO2RR) to produce valuable chemicals, representing one of the most promising ways achieve a neutral cycle. Methane is many products from eCO2RR. Rational design SAC through deliberate coordination regulation and controlled synthesis at low temperatures toward methane production remains very limited. Herein this paper, Cu with four oxygen atoms (Cu-O4) were prepared by soaking nanocrystals on support acetic acid solution 60 °C for 12 h. The structure was revealed extended X-ray absorption fine spectrum photoelectron spectroscopy. Cu-O4 demonstrates excellent activity selectivity towards production, Faradaic efficiency (FE) 63.0% partial current density 200.5 mA cm-2. Theoretical calculation indicates less positive charge center stronger delocalization than Cu-N4 due π bonding interaction SAC, which stabilizes intermediates lowers potential determining step SAC. Strong hydrogen adsorption suppresses evolution may favor hydrogenation methane. limiting that more favored CO, methanol formate, corroborating high This work highlights importance environment steering

<p>High-energy-density jet fuels (HEDJFs) are advanced synthetic liquid hydrocarbons designed to enhance the performance of aerospace vehicles. Compared conventional fuels, HEDJFs have higher density, volume net heat combustion, and lower freezing points. With diminishing fossil resources growing environmental concerns, biomass-derived attracted significant attention. This review highlights recent advancements in synthesizing from lignocellulosic derivatives, focusing on key C-C coupling reactions such as aldol condensation, alkylation/hydroxyl alkylation, Diels-Alder reaction, oligomerization, rearrangement, cyclopropanation, photocatalytic cycloaddition. Approaches producing petroleum-based (e.g., JP-10, RJ-4) derivatives also summarized. Additionally, characteristics various multi-ring analyzed, emphasizing influence molecular structure composition. Furthermore, combustion engine adaptability bio-HEDJFs were Finally, challenges biomass-to-HEDJF synthesis process, reaction efficiency, catalyst activity, cost, etc., outlined. Meanwhile, future research directions proposed, which show that fuel molecules with fused rings, branched chains, low symmetry structures direction. aims advance development efficient methods for HEDJFs.</p>

Abstract Ionic covalent organic frameworks (iCOFs) exhibit unique advantages as heterogeneous catalysts due to their permanent porosity, programmable charge transport, and tunable host‐guest interactions. Here, the fabrication of cationic iCOFs via direct solvothermal assembly integrate zinc ions (Zn(II))‐imine centers are reported construct bifunctional catalysts. The resultant catalyst, Zn@PD‐iCOF, achieves remarkable yields (up 99%) cyclic carbonates in carbon dioxide (CO 2 )‐epoxides cycloaddition reactions under mild conditions (at 80 °C, 0.1 MPa CO ) without need for co‐catalysts solvents, superior most previously ionic This exceptional performance stems from hierarchically ordered pores structure, fully exposed dual active sites (ion pair Lewis acid site), synergistic electronic coupling. Moreover, catalyst retains >90% activity over twelve consecutive cycles, demonstrating stability. study establishes a blueprint designing task‐specific COFs efficient chemical fixation.
