WebMar 25, 2024 · Graphene, a two-dimensional monolayer form of carbon in the sp 2-hybridization state, has attracted a great deal of attention in connection with extensive prospects for its use in electronic devices and composite materials [1, 2].It is natural to suppose that graphene and graphitic materials containing the atoms B–C–N should … WebThe photocatalytic performance of the g-C 3 N 4 nanosheets was measured by degrading RhB under visible-light illumination. The g-C 3 N 4 (30) nanosheets can achieve the highest degradation rate of 88% in 60 min, which is 5 times that of bulk g-C 3 N 4. The mechanisms of the enhancement were studied by discussing the whole photocatalytic process.
