Abstract

We developed a universal method to prepare hydrophilic carbon nitrogen (C 3 N 4 ) nanosheets. By treating C 3 N 4 nanosheets with oxygen plasma, hydroxylamine groups (N–OH) with intense protonation could be introduced on the surface; moreover, the content of N–OH groups increased linearly with the oxygen-plasma treatment time. Thanks to the excellent hydrophilicity, uniformly dispersed C 3 N 4 solution were prepared, which was further translated into C 3 N 4 paper by simple vacuum filtration. Pure C 3 N 4 paper with good stability, excellent hydrophilicity, and biocompatibility were proved to have excellent performance in tissue repair. Further research demonstrated that the oxygen-plasma treatment method can also introduce N–OH groups into other nitrogen-containing carbon materials (NCMs) such as N-doped graphene, N-doped carbon nanotube, and C 2 N, which offers a new perspective on the surface modification and functionalization of these carbon nanomaterials.
