Nitrogen-coordinated metal single atoms catalysts, especially with M-N4 configuration confined within the carbon matrix, emerge as a frontier of electrocatalytic research for enhancing sluggish kinetics oxygen reduction reaction (ORR). Nevertheless, due to highly planar D4h symmetry in M-N4, their adsorption behavior toward intermediates is limited, undesirably elevating energy barriers associated ORR. Moreover, structural engineering substrate also poses significant challenges. Herein, inspired by biological neural network (BNN), reticular nervous system high-speed signal processing and transmitting, comprehensive biomimetic strategy proposed tailoring Fe-N4 (Fe SAs) coupled Fe atomic clusters ACs) active sites, which are anchored onto chitosan microfibers/nanofibers-based aerogel (CMNCA-FeSA+AC) continuous conductive channels an oriented porous architecture. Theoretical analysis reveals synergistic effect SAs ACs optimizing electronic structures expediting The ingenious will shed light on topology optimization efficient electrocatalysts advanced electrochemical conversion devices.
