Abstract Covalent organic frameworks (COFs) have emerged as promising photocatalysts owing to their structural diversity, tunable bandgaps, and exceptional light‐harvesting capabilities. While previous studies primarily focus on developing narrow‐bandgap COFs for broad‐spectrum solar energy utilization, the critical role of interlayer coupling in regulating charge transfer dynamics remains unclear. Conventional monolayer‐based theoretical models inadequately address effects that potentially hindering intralayer electron transport catalytic active sites. This work employs density functional theory (DFT) calculations investigate influence interactions imine‐based COFs. Theoretical analyses reveal bilayer architectures exhibit pronounced interference intramolecular processes which has not been observed monolayer models. Based these mechanistic insights, this designs two isomeric pyrene‐based incorporating identical donor (pyrene) acceptor (nickel bipyridine) units but with distinct strengths. Strikingly, optimized COF weakened demonstrates photocatalytic CO 2 reduction performance, achieving a evolution rate 553.3 µmol g −1 h 94% selectivity under visible light irradiation without additional photosensitizers or co‐catalysts. These findings establish engineering crucial design principle high‐performance COF‐based conversion applications.

Superstructures assembled by subnanometer polyoxometalate (POM) clusters are interesting for their attractive structures and excellent properties. However, the complex interactions between cations make it challenging to control assembly of POM at scale. Here, 20 cluster-assembled superstructures built two types MP

Abstract Strategies that can introduce catalytic auxiliary into electrocatalysts to boost the performance of electrocatalytic CO 2 reduction reaction (CO RR) are meaningful in exploring hybrid systems. Here, a series (Cu NCs@MOF‐545‐M, M=Fe, Co and Ni) have been prepared by assembly Cu NCs with MOF‐545‐M (M=Fe, successfully applied RR. In obtained Ni), integration create system enhances charge transfer efficiency RR activity. Specifically, optimal NCs@MOF‐545‐Co presents remarkable FE over wide potential range (−0.7 V −1.0 V), high generation rate (8.2 mol m −2 h −1 ) excellent maximum energy (69 %, −0.7 which is superior MOF‐545‐Co, represented be one best performances date. This work demonstrates facile approach significantly improve loading metal nanoclusters MOFs, providing valuable reference for future studies on hybridization strategies enhance electrocatalysts.

Abstract Porous organic polymers have shown great potential in photocatalytic CO 2 reduction due to their unique tunable structure favoring gas adsorption and metal sites integration. However, efficient photocatalysis porous is greatly limited by the low surface reactivity electron mobility of bulk structure. Herein, we incorporate TiO nanoparticles Ni(II) into a layered cationic imidazolium polymer (IP), which moieties free anions can stabilize key intermediates enhance reaction kinetics reduction. During reaction, /NiIP situ exfoliated nanosheets (NSs) with more accessible active shorten transport pathways. The formed /NiIP‐NSs exhibit an impressively high production rate as 54.9 mmol ⋅ g −1 h selectivity 99.9 %. embedding could improve efficiency so facilitate photochemical stripping process polymer. Moreover, assistance possess excellent stability during recycling experiments comparison rapidly declined activity NiIP‐NSs. This work presents new strategy construct highly photocatalysts for
