Nature provides an almost limitless supply of sources that inspire scientists to develop new materials with novel applications and less of an environmental impact. Recently, much attention has been focused on preparing natural-product-derived carbon dots (NCDs), because natural products have several advantages. First, natural products are renewable and have good biocompatibility. Second, natural products contain heteroatoms, which facilitate the fabrication of heteroatom-doped NCDs without the addition of an external heteroatom source. Finally, some natural products can be used to prepare NCDs in ways that are very green and simple relative to traditional methods for the preparation of carbon dots from man-made carbon sources. NCDs have shown tremendous potential in many fields, including biosensing, bioimaging, optoelectronics, and photocatalysis. This Review addresses recent progress in the synthesis, properties, and applications of NCDs. The challenges and future direction of research on NCD-based materials in this booming field are also discussed.
大自然提供了几乎无限的资源，激发科学家们开发具有新颖应用和较少环境影响的新材料。最近，人们越来越关注制备天然产物衍生的碳点（NCDs），因为天然产物具有几个优点。首先，天然产物是可再生的，具有良好的生物相容性。其次，天然产物中含有杂原子，这有利于制备杂原子掺杂的 NCDs，而无需添加外部杂原子源。最后，与传统的从人造碳源制备碳点的方法相比，一些天然产物可以用于制备 NCDs，其方法非常绿色和简单。NCDs 在生物传感、生物成像、光电子学和光催化等许多领域显示出巨大的潜力。本文综述了 NCD 的合成、性质和应用的最新进展。还讨论了在这个蓬勃发展的领域中基于 NCD 的材料的挑战和未来研究方向。
