采用不同生物质碳源（淀粉、棉花、葡萄糖、油脂、竹炭）与硝酸铋、钨酸钠在一步微波水热条件下合成了C‐Bi2 WO6复合光催化材料．分别使用XRD、SEM 、FT‐IR和紫外可见分光光度计（U V‐2600）对产物的结构、微观形貌以及光催化性能进行了表征测试．结果表明：棉花、葡萄糖分别与钨酸铋复合所得产物的光催化活性较好，在可见光照射240 min后，对RhB的降解效率分别达到了92％和90．8％．这可能是由于此条件下所得产物的形貌为薄片状且相互堆叠形成了三维层状结构，这种结构增大了光催化剂与有机污染物的接触面积，有利于光催化活性的提高；同时，由红外分析结果可知，碳化棉花与钨酸铋界面之间的协同作用亦有利于光催化活性的提高．

The C‐Bi2 WO6 composite photo‐catalytic materials were synthesized by one‐step microwave hydrothermal using different biomass carbon source (starch ,cotton ,glucose ,oil , bamboo) .The samples of structure ,microstructure ,morphology and photo‐catalytic proper‐ties were characterized by XRD ,SEM ,FT‐IR and UV‐Vis spectrophotometer (UV‐2600) . Results show that when the cotton and glucose composite with Bi2 WO6 ,the photo‐catalytic activity of the sample is the best under visible light irradiation in 240 min ,the degradation ef‐ficiency of RhB reached 92% and 90 .8% ,respectively .T his may be attributed to the mor‐phology of the lamellar sheets stack on each other and form a hierarchical structure ,the con‐tact area of the photo‐catalyst and organic pollutants was increased .That is in favor of in‐crease of photo‐catalytic activity .Meanwhile ,FT‐IR analysis results indicate the interface synergistic effect between cotton and Bi2 WO6 is benefit for photo‐catalytic activity .
