abstract = {To accelerate the large-scale commercialization of
electrochemical energy storage and conversion technologies
through water splitting and regeneration in reversible fuel
cells, cost-effective, highly efficient, and durable
reversible oxygen electrodes are required. We report a
comparatively simple approach to modify a group of
oxygen-evolving perovskites based on lanthanum cobaltite
into effective bifunctional systems through partial atom
substitution, which, upon intermixing with nitrogen-doped
carbon nanotubes, achieve remarkably low round-trip
overvoltage of <850 mV in the electrocatalysis of oxygen
reduction and oxygen evolution in an alkaline electrolyte,
KOH (0.1 m). Besides the bifunctional electrocatalytic
performance, the composite systems with a low Fe content
possessed promising long-term stability.},
