Theory-Guided Regulation of FeN4 Spin State by Neighboring Cu Atoms for Enhanced Oxygen Reduction Electrocatalysis in Flexible Metal-Air Batteries

Ting He et al.

Summary: Iron, nitrogen-codoped carbon nanocomposites have been found to be effective electrocatalysts for the oxygen reduction reaction due to the formation of FeNxCy coordination moieties. Experimental and computational results show that incorporating single Cu sites can decrease the magnetic moment of the Fe centers and significantly enhance ORR activity over a wide pH range. When used as cathode catalysts in aluminum-air and zinc-air batteries, the Fe-N-C nanocomposites exhibit superior performance compared to commercial Pt/C or Pt/C-RuO2 catalysts.

Advances in Graphene-Supported Single-Atom Catalysts for Clean Energy Conversion

Yunkun Dai et al.

Summary: Heterogeneous single-atom catalysts (SACs) have attracted significant attention in electrochemical applications due to their high metal utilization, well-defined active sites, tunable selectivity, and excellent activity. Graphene, with its high surface area, excellent conductivity, and unique electronic properties, has been widely used as a substrate for SACs. This review provides an overview of the synthetic methods for graphene-supported single-atom catalysts (G-SACs), discusses advanced characterization techniques, summarizes recent progress in G-SACs for various electrochemical applications, and presents challenges and outlook for the development of G-SACs with outstanding catalytic activity, stability, and selectivity.

Intrinsic Electrocatalytic Activity Regulation of M-N-C Single-Atom Catalysts for the Oxygen Reduction Reaction

Chang-Xin Zhao et al.

Summary: This Review summarizes 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. The study includes both theoretical calculations and experimental investigations to provide a comprehensive understanding of the structure-performance relationship. Proposed future directions involve developing advanced M-N-C SACs for electrocatalytic ORR and other analogous reactions.

Unraveling the Origin of Sulfur-Doped Fe-N-C Single-Atom Catalyst for Enhanced Oxygen Reduction Activity: Effect of Iron Spin-State Tuning

Zhaoyang Chen et al.

Summary: In this study, sulfur-doped Fe-1-NC catalyst was found to exhibit superior activity towards ORR compared to traditional Fe-NC materials. The incorporation of sulfur in the second coordination sphere of Fe-1-NC was shown to induce a transition of spin polarization configuration, with the low spin single-Fe3+-atom identified as the active site for ORR through operando Fe-57 Mossbauer spectra. Additionally, DFT calculations revealed that the lower spin state of the Fe center after sulfur doping promotes the OH* desorption process.
