Study investigates enhanced electrocatalysis for oxygen reduction in graphene nanoribbons, suggesting improved metal-free catalysts.

Key Points

The study aims to improve the efficiency of oxygen reduction electrocatalysis using nitrogen, sulfur, and boron-doped graphene nanoribbons.
Graphene nanoribbons were codoped with nitrogen, sulfur, and boron using a hydrothermal technique.
Characterization techniques included EELS, FTIR, XPS, and ICP-OES for confirming dopant incorporation.
Raman analysis was conducted to assess defect reconstruction in the carbon lattice.
Nitrogen adsorption-desorption and zeta potential analyses evaluated surface properties.
NSB-GNR showed an onset potential of 0.805 V and a half-wave potential of 0.658 V vs RHE.
Limiting current density was measured at −3.24 mA cm–2 following a four-electron transfer pathway.
Characterization revealed boron located in the inner layers and influenced textural properties, leading to reduced surface area.
