摘　　要：石墨烯量子点(Graphene quantum dots,GQDs)作为一种零维碳纳米材料,不仅具备石墨烯的优异性能,还具有量子限域效应和边界效应,在气体传感检测领域具有重要的应用价值。采用不同的制备方法可得到不同尺寸的GQDs。利用GQDs自身表面丰富的官能团,通过与其它材料复合使其表面进一步功能化,可以满足检测不同气体的要求,拓宽了其在气体传感领域中的应用。本文主要介绍了GQDs的制备方法及其在气体传感领域中的应用进展,并对GQDs在气体传感领域中的应用前景和发展方向进行了展望。Graphene quantum dots(GQDs),as a kind of zero-dimensional carbon nano material,not only have excellent properties of graphene,but also have quantum confinement effect and boundary effect.GQDs with different nano-size can be obtained by various preparation methods.The surface of GQDs has abundant functional groups,which can be further functionalized by compounding with other materials to meet the detection requirements of different gases and broaden its application range in gas sensing.In this review,the preparation methods of GQDs and their applications in gas sensing are introduced.In addition,the application prospect and development direction of GQDs in gas sensing are also prospected.
