Graphitic carbon nitride-based 2D catalysts for green energy: Physical mechanism and applications

Graphite carbon nitride (g-C3N4) has attracted more and more attention, because of its excellent band structure and thermochemical stability, and high efficiency on catalysis. In recent years, g-C3N4 nanostructured photocatalysts have been applied to the fields of energy, environments, and g-C3N4 with different surface morphology, electronic structure, and light absorption range has been widely studied in the field. In this review, we focus on the physical mechanism and summarize recent progress of efficient photocatalysts by adjusting the electronic structure and surface morphology of g-C3N4. Lastly, the challenges and opportunities of g-C3N4 are prospected in the concluding remarks. (C) 2020 Elsevier Ltd. All rights reserved.
