Abstract The efficient activation of small molecules such as H 2 O, CO , and N for sustainable fuel chemical production is a critical challenge in catalysis, owing to the strong covalent bonds (O─H, C═O, N≡N) that resist easy cleavage. Catalysts are pivotal overcoming these energy barriers, enhancing reaction rates selectivity. strategy atomic size misfit, which introduces structural defects like vacancies, grain boundaries, dislocations, has gained attention promising approach optimize catalytic activity. This modulates interactions, alters electronic structures, enhances reactivity active sites, facilitating molecules. Moreover, this holds significant potential reducing environmental impact by enabling more processes. However, current research on misfit remains fragmented, lacking unified framework. A comprehensive review essential consolidate its mechanisms, applications, integration with other tuning methods alloying doping. aims provide valuable insights into design next‐generation catalysts, guiding future developments conversion technologies offering pathways practical, scalable applications molecule activation.

Abstract Single‐atom catalysts (SACs) with unique geometric and electronic configurations have triggered great interest in many important reactions. However, controllably modulating the structure of metal centers to enhance catalytic performance remains a challenge. Here, Ni over 1 ‐NC SACs by introducing electron‐rich phosphorus or electron‐deficient boron for electrochemical CO 2 reduction (CO RR) is systematically tailored. It found that ‐PNC ‐N 3 P site exhibits superior current density 14.6 mA cm −2 Faradaic efficiency 90.6% at −0.8 V versus RHE production, far exceeding ‐BNC SACs. Detailed characterizations theoretical calculations reveal linear relationship between valence state species RR performance. The incorporation facilitates localization around center, significantly promoting adsorption formation key *COOH intermediate RR. This work provides feasible approach quantitatively manipulate single‐atom sites rationally design highly efficient boosted

Abstract Electrochemical CO 2 reduction (denoted as ECO R) technology is expected to transform greenhouse gas into a range of fuels and chemicals combined with renewable electricity. A wide fundamental research has been dedicated the clarification reaction mechanisms developing catalyst materials, which have significantly facilitated level R technology. Nevertheless, still encounters limitations such low utilization efficiency insufficient selectivity high‐value products. Addressing these challenges crucial for be implemented in practical applications. In an electrolysis system, electrolyzer represents core component system primary site. Therefore, composition structure will directly affect performance. This review begins by outlining recent progress at large‐scale level, followed comprehensive analysis industrial configuration, including detailed considerations electrode, diffusion layer, membrane electrolyzer. Finally, we elucidate remaining associated industrialization this offer suggestions advancing it.
