摘要
为了提高有机染料废水降解率,以三聚氰胺和五水硝酸铋为原料,采用静电纺丝方法制备了Bi_(2)O_(2)CO_(3)/g-C_(3)N_(4)复合纳米纤维材料。采用X射线衍射、扫描电子显微镜、傅里叶红外光谱、紫外可见分光光度计等手段对其形貌、结构和光学性能进行了表征。在模拟可见光下,研究了Bi_(2)O_(2)CO_(3)/g-C_(3)N_(4)复合纤维材料对亚甲基蓝的光催化脱色反应和化学稳定性。结果表明:Bi_(2)O_(2)CO_(3)和g-C_(3)N_(4)复合纳米材料的催化降解率效果良好,达到83.2%,是g-C_(3)N_(4)降解率的2倍,重复使用5次后染料的催化活性无明显损失。
In order to improve the degradation of organic dye wastewater,Bi_(2)O_(2)CO_(3)/g-C_(3)N_(4) nanofibers were prepared with melamine and bismuth nitrate pentahydrate as raw materials by electrospinning.The morphology,structure and optical properties were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM)and ultraviolet spectrophotometer.Under simulated visible light,the photocatalytic decolorization and chemical stability of Bi_(2)O_(2)CO_(3)/g-C_(3)N_(4) for methylene blue were studied.The results showed that the catalytic degradation rate of Bi_(2)O_(2)CO_(3)/g-C_(3)N_(4) reached 83.2%,which was twice that of g-C_(3)N_(4).The catalytic activity of the catalyst had no obvious loss after repeated use for 5 times.
