Agri-waste derived electroactive carbon-iron oxide nanocomposite for oxygen reduction reaction: an experimental and theoretical study. RSC Adv 2024; 14:12171-12178. [PMID: 38628491 PMCID: PMC11019505 DOI: 10.1039/d4ra01264j] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 04/12/2024] [Indexed: 04/19/2024] Open
Abstract
Herein, we have utilized agri-waste and amalgamating low Fe3+, to develop an economic iron oxide-carbon hybrid-based electrocatalyst for oxygen reduction reaction (ORR) with water as a main product following close to 4e- transfer process. The electrocatalytic activity is justified by electrochemical active surface area, synergetic effect, and density functional theory calculations.

Abstract
Co@NRPC electrocatalysts with excellent ORR performance were synthesized by pyrolyzing the hybrid precursors. Atomic CoNx and nanosized metallic Co species were active sites. Porous carbon hybrids ensured efficient charge and mass transport.
