摘　　要：利用水热法一步制备了二氧化钛生物质炭复合材料(TiO_(2)/C),并用于光催化降解亚甲基蓝(MB)溶液。使用扫描电子显微镜(SEM),氮气吸脱附实验,X射线光电子能谱(XPS)等方法进行表征。结果显示,TiO_(2)生长过程协同促进了炭材料的比表面积和孔体积增大,TiO_(2)/C对浓度50~300 mg·L^(-1)的MB溶液具有较高去除率,远远高于商品碳毡为载体的复合材料,重复利用四次后去除率仍然达到72%。A composite material of titanium dioxide and biomass carbon(TiO_(2)/C)was prepared by one-step hydrothermal method and used for removal of methylene blue(MB).The TiO_(2)/C composite was characterized by X ray photoelectron spectroscopy(XPS),nitrogen adsorption and desorption experiment,and scanning electron microscopy(SEM).The results show that TiO_(2)/C exhibited superior photodegradation efficiency towards 50~300 mg·L^(-1) MB solution,which is much higher than those of the TiO_(2)/carbon felt composite.Moreover,the degradation efficiency reached 72%during the fourth repetition.
