Coral-like Co₃O₄ Decorated N-doped Carbon Particles as active Materials for Oxygen Reduction Reaction and Supercapacitor.

ABSTRACT: Coral reef has a unique dendritic structure with large specific surface area, rich pore structure, so that it can be attached to a large number of zooxanthellae for gas exchange. Coral reef ecosystems are also known as underwater rainforests. Inspired by this biological structure, we designed and fabricated coral-like Co₃O₄ decorated N-doped carbon particles (Co₃O₄/N-CP). The obtained Co₃O₄/N-CP-900 catalyst shows efficient ORR electrocatalytic performances in an alkaline medium with a positive onset and half-wave potentials of 0.97 and 0.90 V (vs. RHE), as well as a high diffusion-limited current density (5.50 mA cm^-2) comparable to that of a Pt/C catalyst (5.15 mA cm^-2). It also displays better stabil
