Single‐atom catalysts (SACs) with highly active sites atomically dispersed on substrates exhibit unique advantages regarding maximum atomic efficiency, abundant chemical structures, and extraordinary catalytic performances for multiple important reactions. In particular, M–N–C SACs (M=transition metal atom) demonstrate optimal electrocatalytic activity for the oxygen reduction reaction (ORR) and have attracted extensive attention recently. Despite substantial efforts in fabricating various M–N–C SACs, the principles for regulating the intrinsic electrocatalytic activity of their active sites have not been sufficiently studied. In this Review, we summarize the regulation strategies for promoting the intrinsic electrocatalytic ORR activity of M–N–C SACs by modulation of the center metal atoms, the coordinated atoms, the environmental atoms, and the guest groups. Theoretical calculations and experimental investigations are both included to afford a comprehensive understanding of the structure–performance relationship. Finally, future directions of developing advanced M–N–C SACs for electrocatalytic ORR and other analogous reactions are proposed.

Einzelatom‐Katalysatoren (SACs) mit hochaktiven, auf Substraten atomar verteilten Reaktionsstellen haben Vorteile in Bezug auf die maximale atomare Effizienz, die Vielfalt chemischer Strukturen und ihr außerordentliches katalytisches Leistungsvermögen. M‐N‐C‐SACs (M=Übergangsmetallatom) weisen eine optimale elektrokatalytische Aktivität für die Sauerstoffreduktionsreaktion (ORR) auf. Bisher wurden die Prinzipien der Steuerung der intrinsischen elektrokatalytischen Aktivität von M‐N‐C‐Aktivstellen jedoch nicht ausreichend dargestellt. In diesem Aufsatz werden Steuerungsstrategien zur Förderung der intrinsischen elektrokatalytischen ORR‐Aktivität von M‐N‐C‐SACs zusammengestellt, indem jeweils die Metall‐Zentralatome, die koordinierenden Atome, die Umgebungsatome und die Gastgruppen modifiziert werden. Um ein tieferes Verständnis der Struktur‐Leistungs‐Beziehung zu gewinnen, werden theoretische und experimentelle Studien einbezogen. Schließlich werden Richtungen für die weitere Entwicklung von M‐N‐C‐SACs für die elektrokatalytische ORR und andere Reaktionen vorgeschlagen.

“…Due to the unique surface structure, preventing the aggregation of metal atoms is the key challenge to synthesize robust and high-performance SAC. Numerous methods have been applied to construct SAC, including the wet-chemistry method, [33][34][35]47 atomic layer deposition (ALD), 48 MOF-derived method, 49 electro-deposition method, 44 atom trapping, [41][42][43] and so on. The representative methods will be briefly introduced in the following sections.…”
