摘要
研究采用传统Hummers法制备GO(1)和改进Hummers法制备GO(2),并对它们进行SEM、XRD、FTIR表征。结果表明:GO(2)比GO(1)更加的蓬松,在水中分散度更高;GO(2)的氧化程度更高。GO(2)的晶面间距0.80nm,GO(1)的晶面间距0.75nm,两者均远大于石墨原料的0.34nm。GO(1)和GO(2)都成功负载TiO2,在负载过程中被还原成石墨烯(RGO),形成复合材料RGO-Ti O2(1)、RGO-Ti O2(2)。RGO-Ti O2(1))负载的Ti O2的量小于RGO-Ti O2(2),RGO-Ti O2(1)的生成率32.3%大于RGO-Ti O2(2)的28.6%。
GO(1)was prepared by traditional Hummers method and GO(2)was prepared by improved Hummers method,and they were characterized by SEM,XRD and FTIR.The results showed that GO(2)was more fluffy than GO(1)and had higher dispersion in water.GO(2)had a higher degree of oxidation.The crystal plane spacing of GO(2)and GO(1)was 0.80 nm and 0.75 nm,both of which were much larger than the 0.34 nm of graphite raw material.GO(1)and GO(2)were successfully supported with TiO2 and reduced to Reduced Graphene Oxide(RGO)during the supporting process to form composite materials RGO-TiO2(1)and RGO-TiO2(2).The supporting amount of TiO2 on RGO-TiO2(1)was smaller than that of RGO-TiO2(2),and the generation rate(32.3%)of RGO-TiO2(1)was higher than that of RGO-TiO2(28.6%).
