摘　　要：通过原位复合的方法,在石墨烯片层间掺杂纳米银颗粒,制备出石墨烯/银纳米杂化材料(RGO/Ag)。利用紫外吸收光谱、傅里叶红外光谱、透射电子显微镜(TEM)、XRD、拉曼光谱等对氧化石墨烯(GO)、还原氧化石墨烯(RGO)和石墨烯/银纳米杂化材料(RGO/Ag)进行表征。发现复合材料中的银对石墨烯/银材料有拉曼增强作用,结合TEM对这种增强作用进行研究,发现银颗粒的团聚对这种增强作用有减弱作用。Through in-situ composite preparation method,silver nanoparticles were doped in the graphene layers to prepared graphene/silver nano hybrid material. The graphene oxide,reduction of oxide graphene and graphene/silver nano hybrid material were characterized by UV-Vis,FTIR,XRD,TEM and Raman spectrum. The results show that Ag can enhanced the Raman signal of reduced graphene oxide/silver nanocomposites. Then,illustrate this problem combined with TEM. Found the reunite of Ag particle can ease the enhancement effect.
