Graphene quantum dots which are known as zero-dimensional materials are gaining increasing attention from researchers all over the world. This is predicated upon their relatively unique chemiluminescent, fluorescent, electrochemiluminescent, and electronic properties. The precise mechanism of electrochemiluminescence continues to be a subject of debate in the research world, and this is important in identifying synthetic pathways for graphene quantum dots. Heavy metals and other emerging pollutants are global health and environmental concerns. Several studies have reported the sensitivity and limit of detection of graphene quantum dots up to the nano-, pico-, and femto- levels when used as sensors. This review seeks to bridge information gaps on the reported electrochemiluminescence chemosensors for emerging pollutants using graphene quantum dots under the sub-headings, synthesis, characterization, electrochemiluminescence chemosensor detection, and comparison with other detection methods.
石墨烯量子点被称为零维材料，正受到来自世界各地研究人员的越来越多的关注。这是基于它们相对独特的化学发光、荧光、电致化学发光和电子性质。电致化学发光的确切机制在研究界仍然是一个争论的话题，这对于确定石墨烯量子点的合成途径很重要。重金属和其他新兴污染物是全球健康和环境关注的问题。几项研究报告了石墨烯量子点作为传感器的灵敏度和检测限可达纳米、皮米和飞米水平。本综述旨在弥合使用石墨烯量子点作为电化学发光化学传感器检测新兴污染物的报告中的信息空白，内容分为以下小标题：合成、表征、电化学发光化学传感器检测以及与其他检测方法的比较。
