首次使用真菌纤维为模板，利用溶剂热法，以CdCl2和硫脲为原料，在不同温度条件下制备真菌纤维/硫化镉复合纤维材料.通过 SEM、FT-IR、XRD等表征手段对所制备的真菌纤维/硫化镉复合纤维材料进行物化结构分析.结果发现，真菌纤维通过自身表面含有的活性官能团与金属离子发生配位、协调等作用，使CdS颗粒能够在真菌纤维表面稳定成核并生长成型，得到了分布均匀、晶粒尺寸为20 nm 左右、球形的CdS纳米颗粒.通过对苯酚的光降解实验表明，在150℃条件下制备的真菌纤维/硫化镉复合纤维材料对苯酚的光降解率可高达99．23％，真菌纤维/硫化镉复合纤维材料具有优异的光催化降解性能.

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 character-ized 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 experi-ment of phenol showed that the phenol photodegradation rate of fungus fiber/CdS composite fiber material pre-pared under the 150 ℃ could reach to 99.23%,demonstrating the excellent photocatalytic degradation property.
