Graphitic phase
WebGraphitic carbon nitride nanosheets are extracted, produced via simple liquid-phase exfoliation of a layered bulk material, g-C 3 N 4. The resulting nanosheets, having ≈2 nm thickness and N/C atomic ratio of 1.31, show an optical bandgap of 2.65 eV. WebTherefore, graphitic carbon nitride (g-C 3 N 4) as a material has gained wide attention due to its relative ease of synthesis, high nitrogen content, conductivity, and tuneable band gap energy. In recent years, their tunable electronic properties along with physicochemical stability have given rise to numerous research delving into their ...
