Since its discovery little more than a decade ago,1 the two-dimensional (2D) allotrope of carbon—graphene—has been the subject of intense multidisciplinary research efforts.

Graphene's unique properties spark interdisciplinary interest; its honeycomb structure offers electrical, optical, and mechanical marvels.

Graphene nanoribbons (GNRs) are quasi-one-dimensional narrow strips of graphene comprised of sp2-hybridized carbon atoms arranged into hexagonal honeycomb lattice configurations.

Catalytic water splitting produces hydrogen crucial for renewable energy, petroleum refining, and chemical industry applications like methanol production.
