Efficient Metal‐Free Electrocatalysts from N‐Doped Carbon Nanomaterials: Mono‐Doping and Co‐Doping

Abstract

N‐doped carbon nanomaterials have rapidly grown as the most important metal‐free catalysts in a wide range of chemical and electrochemical reactions. This current report summarizes the latest advances in N‐doped carbon electrocatalysts prepared by N mono‐doping and co‐doping with other heteroatoms. The structure–performance relationship of these materials is subsequently rationalized and perspectives on developing more efficient and sustainable electrocatalysts from carbon nanomaterials are also suggested.

Biomass Derived Graphene‐Like Carbons for Electrocatalytic Oxygen Reduction Reaction

“…Among those candidates, the N‐doped carbon material as a representative metal‐free catalyst is of particular interest . Alien nitrogen atom doped into the graphitic framework changes electronic density of carbon surface and thus favors the oxygen molecule adsorption and further reduction ,. Despite of the high activity of N‐doped carbons, their performances are still far from satisfactory ,,.…”

Metal‐free graphene/boron nitride heterointerface for CO2 reduction: Surface curvature controls catalytic activity and selectivity

“…For example, B‐doped graphene has been applied as a metal‐free catalyst for N 2 fixation with a low overpotential . A series of N‐doped graphene materials have been realized in many electrocatalytic reactions, such as oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and CO 2 reduction reaction . These dopants and their doping methods play a significant role in catalyzing chemical reactions, compared to two disparate materials .…”
