Graphene quantum dots (GQDs) are 0D materials belonging to the carbon-based family that present some interesting characteristics of graphene combined with a tunable bandgap emerging from their reduced size, which gives them final outstanding physical–chemical properties. Furthermore, GQDs can be combined with other materials to produce nanocomposites with remarkable properties and superior performance. In this review, we present a timely survey on how the structural characteristics and physical–chemical properties of GQDs enable their use in advanced composite materials for agricultural and environmental applications. Specifically, emphasis is given to GQD-based composites in the form of films, nanofibers, aerogels, and molecularly imprinted polymers. The unique properties of GQD nanocomposites are suitable for designing devices employed in: i) filtration membranes and adsorbent materials for contaminant removal; ii) optical devices and (bio)sensors with different transduction modes for detecting hazardous analytes including pesticides, heavy metals, antibiotics, and food contaminants; iii) and novel catalyst systems for degrading pollutants. Finally, current challenges and future prospects on industrial applications of GQD-based composites are also discussed.

石墨烯量子点及其纳米复合材料的综述：从实验室合成到农业和环境应用

石墨烯量子点（GQD）是属于碳基族的0D材料，具有石墨烯的一些有趣特征，并且由于其尺寸减小而出现了可调节的带隙，从而使它们具有最终的出色物理化学性能。此外，GQD可以与其他材料组合以生产具有卓越性能和卓越性能的纳米复合材料。在本文中，我们对GQD的结构特征和物理化学特性如何使其在农业和环境应用的高级复合材料中使用进行了及时的调查。具体来说，重点是薄膜，纳米纤维，气凝胶和分子印迹聚合物形式的基于GQD的复合材料。GQD纳米复合材料的独特性能适用于设计用于以下方面的设备：i）过滤膜和吸附材料，用于去除污染物；ii）具有不同转换模式的光学设备和（生物）传感器，用于检测有害分析物，包括农药，重金属，抗生素和食品污染物；iii）和用于降解污染物的新型催化剂体系。最后，还讨论了基于GQD的复合材料在工业应用中的当前挑战和未来前景。
