Title:: Preparation of Ag-Graphene Composites and Detection of SERS Performance

摘要:: 近年来，石墨烯由于其出色的理化性质吸引了科学界的眼球，成为材料中飞速发展的佼佼者。现如今，在很多复合材料中，石墨烯都起到了至关重要的作用，它不仅成为支撑材料的二维碳质载体，也是不可或缺的功能性有效组分。独特的平面结构、较大的比表面积以及超高的电子转移率赋予石墨烯卓越的机械力学、电学丶热学和磁学性能。而石墨烯与贵重金属制备的二元复合材料更是引起了各界的广泛关注，利用石墨烯的特性，在其表面负载具有功能性的Ag粒子，从而制备出灵敏度高的活性SERS基底，相信这种检测方式会对水环境中芳香胺类有机污染物的研究起到了重大作用。

Abstract:: In recent years, graphene has attracted the attention of the scientific community due to its excellent physical and chemical properties, and it has become a leader in the rapid development of materials. Today, graphene plays a crucial role in many composite materials. It not only becomes a two-dimensional carbonaceous support for supporting materials, but also an indispensable functional effective component. The unique planar structure, large specific surface area, and high electron transfer rate give graphene excellent mechanical, electrical, thermal and magnetic properties. The binary composite materials prepared from graphene and precious me＜x＞tals have attracted wide attention from all walks of life. Using the characteristics of graphene, functional Ag particles are loaded on their surface area, thereby producing highly sensitive active SERS. The substrate is expected to be applied to the detection of aromatic amine organic pollutants in the current water environment
