摘要：

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-C3 N4 -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-C3 N4 -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-C3 N4 -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. © 2024 Cailiao Daobaoshe/ Materials Review.
