Lanthanum‐Induced Gradient Fields in Asymmetric Heterointerface Catalysts for Enhanced Oxygen Electrocatalysis

Advanced Materials, EarlyView.
Uncontrolled atomic migration during the pyrolysis of metal‐N‐C catalysts often leads to disordered coordination environments, active site loss, and poor oxygen electrocatalytic activities. Herein, a La‐mediated atomic migration strategy enables the fabrication of a well‐defined asymmetric heterostructure (LaN/LaFe‐NC) featuring a built‐in electric ...
