Abstract:
... Metal-free g-C3N4 is always limited by low surface area, rapid charge recombination and limited visible light absorption. In this study, novel porous nitrogen self-doped g-C3N4 nanosheets were prepared by a combination of N self-doping and thermal exfoliation process. Compared to the bulk g-C3N4, N self-doped g-C3N4 nanosheets possessed a high specific surface area of 74.79 m2 g−1, enhanced visibl ...
