Carbon microspheres were successfully fabricated by hydrothermal method using glucose as raw material.The sizes of microspheres and their adsorption properties were controlled by adjusting the concentration of glucose and the addition of acrylamide;meanwhile, the carbon microspheres were applied to dye adsorption and photocatalytic degradation.The SEM images showed that the diameters of carbon microspheres reduced with the increase of glucose concentration, and effectively reduced with the addition of acrylamide.The experiments results of dye adsorption and photocatalytic degradation demonstrated that the carbon microspheres synthesized via the addition of acrylamide resulted in better properties of methylene blue adsorption and photocatalytic degradation, and the degradation efficiency of methylene blue reached approximate 90 % within 2 h.%本文以葡萄糖为原料、采用水热法制备了碳微米球,通过改变葡萄糖的浓度及添加丙烯酰胺调控碳微米球的粒径大小及吸附性能,并将其应用于吸附与光催化降解亚甲基蓝染料废水的研究.扫描电镜(SEM)结果表明,随着葡萄糖浓度的增加,碳微米球的平均粒径减小,丙烯酰胺的加入促进了碳微米球粒径的减小.染料吸附及光催化降解实验结果表明,添加丙烯酰胺后的碳微米球表现出良好的吸附及光催化降解性能,2 h内亚甲基蓝可以分解近90 %.
