WebGraphitic carbon nitride (g-C3 N 4) is a conjugated polymer having a graphite-like structure, with fragile van der Waals forces between the layers and with every layer having strong C N bonding. Pristine g-C 3 N 4 shows less effectiveness in visible light owing to the wide bandgap and less specific surface. Structure. Graphite consists of sheets of trigonal planar carbon. The individual layers are called graphene. In each layer, the carbon atoms are arranged in a honeycomb lattice with a bond length of 0.142 nm, and the distance between planes is 0.335 nm. See more Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are … See more Graphite occurs in metamorphic rocks as a result of the reduction of sedimentary carbon compounds during metamorphism.
