摘要: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性能吸附及光催化降解,2 h内亚甲基蓝可以分解近90%。

Abstract:Carbon microspheres were successfully fabricated by hydrothermalmethod using glucose as raw material. The sizes of microspheres and theiradsorption properties were controlled by adjusting the concentration of glucoseand the addition of acrylamide; meanwhile, the carbon microspheres were appliedto dye adsorption and photocatalytic degradation. The SEM images showed thatthe diameters of carbon microspheres reduced with the increase of glucoseconcentration, and effectively reduced with the addition of acrylamide. Theexperiments results of dye adsorption and photocatalytic degradationdemonstrated that the carbon microspheres synthesized via the addition ofacrylamide resulted in better properties of methylene blueadsorption and photocatalytic degradation, and thedegradation efficiency ofmethylene blue reached approximate 90 % within 2 h.
