Abstract In this work, four g-C₃N₄ photocatalysts including irregular loose flakes g-C₃N₄-4, granular g-C₃N₄-8, tubular g-C₃N₄-24 and irregular tubular g-C₃N₄-32 were prepared. The results of XRD and XPS proved that four g-C₃N₄ photocatalysts were successfully prepared. The results of the photoelectric performance tests showed that the hollow tubular g-C₃N₄-24 had good visible light response, minimal impedance and best photocurrent response, indicating the best separation of photogenerated electrons and holes. The photocatalytic degradation performance of g-C₃N₄-24 photocatalyst was investigated by using fuchsin basic as a simulated pollutant, and the results showed that the degradation of basic magenta could reach 86.7% within 90 min under the conditions of visible light. Finally, the mechanism of g-C₃N₄-24 photocatalyst was investigated based on the active species capture experiment, and it was found that ·O₂^-,h⁺ and ·OH were all active species in the degradation process of fuchsin basic, with ·O₂^- being the most dominant active species.
