Abstract Large amounts of CO 2 have disrupted the natural carbon cycle. reduction reaction (CO RR) is an effective strategy to reduce high concentration . Currently, design cathode catalyst widespread promote RR. However, effect electrolyte on catalytic fuzzy. Hence, silver nanoparticles (Ag NPs) synthesized conveniently by a one-pot method was used study effects different electrolytes activity and selectivity in 0.1 M NaHCO 3 , KHCO KCl as were applied into Efficient RR performances are exposed three electrolytes. The results show that optimal choice with maximum over 80%, which better than many reports. Meanwhile, enhances but poisons active site weaken selectivity. This research affords direction for acquainting oneself exploit new energy.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 26, 2025

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.
