Graphite edges exhibit distinct chemical and electronic properties
Multiple studies demonstrate that graphite and graphene edges possess distinct electronic structures and enhanced chemical reactivity compared to basal planes.
The retrieved literature consistently confirms that graphite edges (such as zigzag and armchair configurations) host unique electronic states and localized active sites that drive distinct chemical behaviors, such as radical reactions and enhanced adsorption.
