A novel and straightforward operation was used to graft the p-nitrobenzoic acid (PNA) to the terminal of graphitic carbon nitride (g-C3N4) by incorporating carbanyl and amido groups. The synthesized product possessed good performance in the photo-degradation of rhodamine B (RhB). FTIR and XPS results showed that PNA has successfully grafted onto g-C3N4. Optical tests indicated the band gap of g-C3N4 narrowed after being modified, greatly improved separation efficiency of electric carriers. According to the experimental results, the photo-degradation rate of RhB increased significantly, and the degradation efficiency was about five times higher than that of the pristine g-C3N4.
