| Abstract | Chemical scissors provide a new vision to manufacture unique carbon nitride nanostructures with improved photocatalytic performance. Herein, graphitic carbon nitride nanoribbon (GCNR), with a typical length of 1.75 μm, width of 210 nm and thickness of 3 nm, was obtained by acid treatment of bulk g-C3N4 with HNO3/H2SO4 mixtures. The C/N molar ratio of GCNR (around 0.629) was much smaller than that of pristine g-C3N4 (0.758). It was demonstrated that larger amounts of carbon vacancies on the ultra-thin ribbon structures could contribute to improved electron–hole separation efficiency and excellent photocatalytic H2 production. The average H2 production rate of GCNR under visible light was 49.4 μmol h−1, which was 20 times that of the original catalyst. |
