The Sono-Photocatalytic Performance of PAN/g-C(3)N(4)/CdS Nanofibers Heterojunction

The Polyacrylonitrile (PAN)/g-C(3)N(4)/CdS nanofiber sono-photocatalysts were successfully synthesized by an ordinary electrospining-chemical deposition method. The PAN/g-C(3)N(4)/CdS heterojunction nanofibers constructed with the CdS nanoparticles deposited on the PAN/g-C(3)N(4) nanofibers. The g-C(3)N(4)/CdS heterojunction increase of light absorption and the construction of heterojunction can depress recombination of charge carrier and PAN nanofibers improve the recyclability successfully. Finally, a highly effective photocatalytic activity was performed by degradation of Rhodamine B (RhB) in visible light irradiation. Furthermore, an ultrasonic method is introduced into the sono-photocatalytic system to enhance the degradation efficiency of RhB ascribed to the synergistic effect of ultrasound.
