Abstract Numerous in situ characterization studies have focused on revealing the catalytic mechanisms of single‐atom catalysts (SACs), providing a theoretical basis for their rational design. Although research is relatively limited, stability SACs under long‐term operating conditions equally important and prerequisite real‐world energy applications, such as fuel cells water electrolyzers. Recently, there has been rise destabilization regeneration SACs; however, timely comprehensive summaries that provide catalysis community with valuable insights directions are still lacking. This review summarizes recent advances strategies SACs, specifically highlighting various state‐of‐the‐art techniques employed studies. The factors induce identified by discussing failure active sites, coordination environments, supports, reaction scenarios. Next, primary introduced, including redispersion, surface poison desorption, exposure subsurface sites. Additionally, advantages limitations both ex discussed. Finally, future proposed, aimed at constructing structure–stability relationships guiding design more stable SACs.

With the increasing demand for downstream ammonia products, research on fuel has received growing attention. Therefore, under "dual carbon" context, it is crucial to develop an energy-efficient and environmentally friendly method synthesis. Current indicates that electrocatalytic synthesis one of most promising methods. This study systematically summarizes three major factors influencing nitrogen reduction reaction (eNRR) catalysts synthesis: material optimization, structural design, engineering. In terms materials, precious-metal-based, non-precious-metal-based, metal-free eNRR are classified listed. By examination properties catalytic effects various metals non-metals in synthesis, materials with highest activity can be further identified. To enhance efficiency, strategies, such as vacancy creation, doping, interface engineering, facet changes size morphology active sites, have been summarized. integration reactions, including microscale activation, proton transfer, electron efficiency was discussed depth. Finally, urgent issues need addressed current were discussed, unique insights future development provided. review aims provide innovative ideas design improve rate selectivity catalysts.

Nitrogen (N2) activation and the hydrogen evolution reaction pose significant limitations on electrocatalytic nitrogen reduction (NRR) performance. The exclusive electronic structure of main group elements has advantage inhibiting generation in electrochemical NRR. However, poor conductivity activity remain obstacles to its application. Herein, we report a combination strategy cation-induced amorphous Ga2O3 nanofibers heterostructure engineering, thereby effectively enhancing amorphization generates more oxygen vacancies that enhance N2 electron transfer ability. Additionally, by constructing heterogeneous structures drive charge transfer, enrich electronics surface a-Ga2O3 increase their catalytic activity. Thus, a-Ga2O3/MXene deliver NH3 yield 50.00 μg h-1 mg-1 FE 19.13% at -0.35 V. We anticipate these findings will offer new reference value for further ammonia synthesis research materials.
