中文摘要：

以绿色、无毒的柠檬酸三钠和硼氢化钠为还原剂通过微波液相加热还原氧化石墨（GO）制备石墨烯（RGO），采用X射线衍射、紫外-可见吸收光谱、拉曼光谱、透射电镜对制备的RGO样品进行了表征，并以罗丹明B为目标降解物，研究了RGO在白光照射条件下的催化降解效果．研究结果表明：2种还原剂都可还原GO生成石墨烯，且硼氢化钠比柠檬酸三钠的还原程度高，所制备的石墨烯无序度更高；由柠檬酸三钠弱还原制备的石墨烯由于强大的吸附本领，其光催化降解效果最好．

英文摘要：

Using nontoxic green trisodium citrate and sodium borohydride as reducer, graphene has been prepared by microwave heating to reduce graphite oxide （GO）.X-ray diffraction （XRD）, UV Vis absorption spectrum,Raman spectroscope and transmission electronic election microscope （TEM） were used to characterize the sample prepared.Their catalytic degradation effect for degrading rhodamine B was investigated under the condition of white light illumination.The results indicate that Graphite oxide has been reduced by the two kinds of reducer. The graphene（RGO） reduction degree and disorder by sodium borohydride is higher than that of trisodium citrate. The photocatalytic degradation effect of RGO by trisodium citrate is best because of the strong adsorptive capacity.
