S-block single atoms represent an ideal catalyst for the oxygen reduction reaction (ORR) as they can suppress Fenton reaction. However, symmetry of s/p orbitals tends to generate either excessively strong or weak interaction with intermediates. Herein, Ca coordinated -S, -OP, and three N (Ca/NPS-HC) were fabricated modulate adsorption intermediates promote efficiency s-block ORR catalysts. The experimental results from demonstrated that Ca/NPS-HC exhibited outstanding catalytic capability a half-wave potential 0.89 V, kinetic current density 56.6 mA cm

Abstract Fe single‐atom on N‐doped carbon (FeN‐C) catalysts emerge as promising alternatives to commercial Pt/C for the oxygen reduction reaction. Heterogeneous atom doping is proposed be effective modulating catalyst performance. Despite this, relationship between fine coordination structure of doped atoms and catalytic activity central metal site remains poorly understood. Herein, with S in either first shell (FeSN–C) or second (FeN–SC) active are synthesized compare effects different structure. FeN–SC exhibits prominent performance a half‐wave potential 0.92 V rotating disk electrode peak power density 251 mW cm −2 zinc–air battery. Theoretical studies reveal that effectively modulates electronic charge transfer at center. Compared directly coordinated within shell, located more optimizing adsorption desorption energy barriers oxygen‐containing intermediates sites. This study provides new strategy adjust by engineering multilayer center catalyst.

Electrochemical reduction reactions, as cathodic processes in many energy-related devices, significantly impact the overall efficiency determined mainly by performance of electrocatalysts. Metal-organic frameworks (MOFs) derived carbon-supported metal materials have become one star electrocatalysts due to their tunable structure and composition through ligand design screening. However, for different electroreduction required active species vary phase component, electronic state, catalytic center configuration, hence requiring effective customization. From this perspective, review comprehensively analyzes structural principles, loading strategies, practical performance, complex mechanisms, thereby providing insights guidance future rational such catalysts.
