Bamboo fiber molecular-assisted engineering realizes carbon-doped g-C3N4 for efficient photocatalytic degradation of tetracycline

Abstract

How to make full use of bamboo fiber resources to achieve molecular-assisted engineering of C-doped g-C3N4 to improve the photocatalytic effect is challenging. In this paper, a series of Carbon- doped g-C3N4 were successfully designed and prepared through bamboo fiber molecular assembly strategy, which could be used as efficient high-efficiency photocatalysts for degradation of tetracycline. Taking tetracycline (TC) as a model pollutant, the photocatalytic efficiency of Carbon- doped g-C3N4 was significantly enhanced. Among them, the material of Carbon-doped g-C3N4 (labeled as CCN-2.5) shows the best photocatalytic performances with the fastest photocatalytic degradation efficiency of TC. And the degradation rate is 4.16 times of the original g-C3N4. After five cycle experiments, the CCN-2.5 still exhibits high stability and high catalytic activity. The results develops a low-cost and green method for preparing C-doped g-C3N4 from bamboo fiber resources, enriching and developing the scientific connotation and application of bamboo fiber.
