Nitrogen- and Oxygen-Doped Graphene Structure Diagram #9107 (License: Personal Use)

This diagram illustrates a hexagonal graphene lattice with selective substitution of carbon atoms by nitrogen (N) and oxygen (O) heteroatoms, marked in blue. Red bonds form the sp²-hybridized carbon network, while blue dotted lines denote directional electron transfer between dopant sites, emphasizing enhanced conductivity and catalytic activity. The highlighted pentagonal defects suggest localized strain and reactivity hotspots critical for electrochemical applications.

Used in academic publications, educational resources, and materials science websites to explain heteroatom-doped carbon nanomaterials; targets researchers and students seeking visual insight into graphene functionalization for batteries, sensors, or catalysts.
