摘要

绿色还原剂在制备还原氧化石墨烯（rGO）中的作用研究已经成功完成。氧化石墨烯（GO）的还原是使用各种还原剂如抗坏血酸（rGO AA）、没食子酸（rGO AG）和柠檬酸三钠（rGO NS）进行化学还原的。GO是使用Tour方法在65℃的温度下制备的？在高锰酸钾∶石墨重量比为1:3.5的条件下反应6小时。结果表明，rGO-AA的电导率最高，为755.70S/m，具有比表面积为255.93m2/g、孔体积为0.61cm3/g、平均孔径为7.10nm、ID/IG比为1.93、材料纳米结构堆叠中有三层石墨烯等特性。因此，可以得出结论，抗坏血酸还原GO（rGO-AA）是产生rGO最有效的方法。

Study of green reductant effects of highly reduced graphene oxide production and their characteristics

The study of the green reductant effects to produce reduced graphene oxide (rGO) has been completed successfully. The reduction of graphene oxide (GO) was carried out chemically using various reductants such as ascorbic acid (rGO-AA), gallic acid (rGO-AG), and trisodium citrate (rGO-NS). The GO was prepared using the Tour method at a temperature of 65 ? for 6 hours with potassium permanganate: graphite weight ratio 1:3.5. The results showed that rGO-AA had the highest electrical conductivity value of 755.70 S/m, with characteristics such as a surface area of 255.93 m2/g, a pore volume of 0.61 cm3/g, an average pore diameter of 7.10 nm, ID/IG ratio of 1.93, and three graphene layers in the material nanostructure stack. Therefore, it can be concluded that the reduction of GO with ascorbic acid (rGO-AA) is the most effective in producing rGO.
