Graphitic carbon nitride (g-C<SUB>3</SUB>N<SUB>4</SUB>), as a metal-free and visible light-responsive photocatalyst in the field of solar energy conversion and environmental remediation, has become a hot spot and has attracted widespread interdisciplinary attention [1], thanks to its unique electronic band structure, high physical and chemical stability and rich earth properties. This important review summarizes the latest developments related to the design and construction of original g-C<SUB>3</SUB>N<SUB>4</SUB> and g-C<SUB>3</SUB>N<SUB>4</SUB>-based nanocomposites, including (i) the nano architecture design of bare g-C<SUB>3</SUB>N<SUB>4</SUB>, such as hard and soft templates methods, supramolecular pre-organization assembly, exfoliation and template-free synthesis; (ii) functionalization of g-C<SUB>3</SUB>N<SUB>4</SUB> by element doping or copolymerization, and (iii) formation of heterostructures/junctions. The structure and characteristics of each classification of the heterojunction system will be strictly reviewed, namely metal-g-C<SUB>3</SUB>N<SUB>4</SUB>, semiconductor-g-C<SUB>3</SUB>N<SUB>4</SUB>, homotype g-C<SUB>3</SUB>N<SUB>4</SUB>/g-C<SUB>3</SUB>N<SUB>4</SUB>, graphitic carbon-g-C<SUB>3</SUB>N<SUB>4</SUB>, conductive polymer-g-C<SUB>3</SUB>N<SUB>4</SUB>, sensitizer-g-C<SUB>3</SUB>N<SUB>4</SUB> and multi-component heterojunction. This Viewpoint outlines the latest major developments in high-performance g-C<SUB>3</SUB>N<SUB>4</SUB>-based photocatalysts designed to generate hydrogen under visible light irradiation. Describes reasonable strategies, such as nanostructure design, band gap engineering, dye sensitization, and heterostructure fabrication. Finally, this Viewpoint focuses on the challenges and opportunities faced by the future development of g-C<SUB>3</SUB>N<SUB>4</SUB>-based photocatalysts in the exciting research field.
