Fungus fiber/CdS composite fiber materials and their photocatalytic performance

In this paper,we firstly used the fungus fiber as a template,and adopted the solvothermal method for preparing the fungus fiber/CdS composites fiber material under different temperature conditions with CdCl2 and thiourea as raw materials.The fungus fiber/CdS composite fiber material that had been obtained was characterized by scanning electron microscopy(SEM),fourier transformed infrared(FT-IR),and X-ray diffraction(XRD).The results indicated that the spherical CdS nanoparticles were homogeneous distribution,with the size of the grain was about 20 nm,which were stable in the course of nucleation and grew on the surface of fungus cellulose due to the coordination effect with active group.The investigation of photocatalytic degradation experiment of phenol showed that the phenol photodegradation rate of fungus fiber/CdS composite fiber material prepared under the 150℃could reach to 99.23%,demonstrating the excellent photocatalytic degradation property.
