- The g-C3N4 wrapping on CNFs carrier to form g-C3N4/CNFs, which was prepared successfully.
- The g-C3N4/CNFs can be easily used in the next reaction because of the existence of CNFs membrane.
- The g-C3N4/CNFs prepared by gas-solid method make the g-C3N4 can load on CNFs uniformly.
- The g-C3N4/CNFs exhibited excellent adsorption performance and photocatalytic activity to various organic dyes.
A composite catalyst that graphite carbon nitride/carbon nanofibers (g-C3N4/CNFs) was successfully prepared through electrospinning technology, high-temperature calcination process and gas-solid method. The morphology and structure of g-C3N4/CNFs were investigated through some characteristics, indicating the composite that g-C3N4 wrapping on one-dimensional carbon fiber has been synthesized successfully. Furthermore, the experiments for degradation of different dyes with the photocatalyst under the irradiation of UV and visible light were carried out, showing that the composite catalyst has the synergy effects of adsorption and photocatalysis which are belonged to CNFs and g-C3N4 respectively. Furthermore, the recycle experiments of the catalyst for degrading dyes under the UV and visible light irradiation were also carried out and indicated that the catalyst had an excellent stability and cycle performance. Above all, as-prepared g-C3N4/CNFs catalyst had a potential appliance value in the degradation of organic pollutants in water.
