Efficient ORR electrocatalytic activity of peanut shell-based graphitic carbon microstructures

Abstract

Dual-doped graphitic carbon CoOP@bio-C with hierarchical microporous structures was prepared from a sustainable waste biomass, peanut shell, with CO₂ gas as the activating agent through a thermal-reduction method. The resulting material displays an overall superior electrocatalytic activity for the ORR to commercial Pt/C.
