Layered graphitic carbon nitride: nano-heterostructures, photo/electro-chemical performance and trends

As an organic semiconductor, graphitic carbon nitride (g-C3N4) nanosheets have been developed into a highly active photocatalyst for H2O splitting generating H2 under visible light irradiation condition and for reduction of CO2. The photo/electro-chemical performances are dependent on the porous structure, morphology, thickness, and crystallinity of the materials. Construction of g-C3N4 heterojunctions can be vital in enhancing catalytic...
