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.
