FeS2/C复合材料的制备及其结构与形貌分析

Synthesis and structure and morphology analysis of FeS_2/C composite material

以草酸亚铁、硫脲和升华硫为主要原料,采用水热法制备FeS_2/C复合材料。优化了草酸亚铁、硫脲和升华硫的摩尔比,分别探讨了硫脲、升华硫和抗坏血酸的加入量对FeS_2/C复合材料的组成、结构和形貌的影响,并且探讨了柠檬酸、蔗糖、聚乙二醇3种不同的碳源对制备得到的FeS_2/C复合材料的影响,由此对碳源含量和种类进行优化和选择。

Sythesizing FeS2/C composite material used ferrous oxalete,thiourea and sulfur as raw materials by hydrothermal method.Researching on the influence of addition of thiourea and sulfur on the synthesis of FeS2/C.Besides,analyzing the influence of addition of ascorbic acid and different carbon source on the synthesis,structure and morphology of FeS2/C composites.The results showed that 1∶4∶5was the optimum proportion and the optimum addition of ascorbic acid was 0.375 g for our system.
