摘要： 以葡萄糖为原料制备的磺化碳材料作为Fenton反应过程中固体酸及载体,研究了磺化碳材料结构对Fe2+的负载能力及其对甲基橙降解反应的催化性能. 结果表明,直接加热法制备的磺化碳材料呈致密块状结构,对Fe2+几乎没有负载能力; 而水热法制备的磺化碳材料呈相互胶联的纳米粒子,室温下对甲基橙表现出较好的降解性能(甲基橙降解率可达79%以上). 反应过程中溶液的pH=2.4～3.2, 在碳材料中引入-SO3H基实现了固体酸代替液体酸的目的.

Abstract: The sulphonated carbon materials made from glucose were used as the solid acid i n Fenton reaction, and the effects of the structure of the carbon materials prep ared by different methods on the degradation efficiency of methyl orange were me asured. The Fe2+ activated sulphonated carbon catalyst prepared by the hyd rothermal metho d exhibited better catalytic performance than that prepared by the direct heatin g method.
