Sulfate Oxyanion Steered d‐Orbital Electronic State of Nickel‐Iron Nanoalloy for Boosting Electrocatalytic Performance

Oxyanion groups recently offer an innovative avenue for improving the sluggish kinetics of electrochemical reactions benefitting from their particular polyanion configurations and large electronegativity. Nevertheless, the exact structure design and deep regulating mechanism of oxyanion species remain poorly understood. Herein, a fresh architecture of the sulfate oxyanion coordinated nickel-iron nanoalloy on nitrogen and sulfur co-doped carbon nanotube (SO
