摘要
以钛酸四丁酯为钛源,采用水热合成法制备了TiO2-GO纳米复合材料.通过FT-IR,SEM,TEM等实验分析方法对新材料进行表征.选择模拟染料亚甲基蓝溶液对TiO2-GO的降解能力进行考察,最终确定最佳条件为:在染料初始质量浓度为15 mg·L^-1,pH为4,催化剂用量为20 mg的条件下,对亚甲基蓝染料的最大降解率为80.65%.
Tetrabutyl titanate was used as the titanium source,and TiO2-GO nanocomposites were prepared by hydrothermal synthesis.The new materials are characterized by FT-IR,SEM,TEM and other experimental analysis methods.The simulated dye methylene blue solution was selected to investigate the degradation ability of TiO2-GO,and the best conditions were finally determined as follows,the initial dye concentration is 15 mg·L^-1,the pH is 4,and the catalyst dosage is 20 mg.The maximum degradation rate of Methylene blue is 80.65%.
