The contamination of the environment by domestic and industrial discharges is a relevant and persistent problem that needs novel solutions. Innovations in the detection, adsorption, and removal or in-situ degradation of toxic components are urgently required. Various effective techniques and materials have been proposed to address this problem, in which carbon dots (CDs) stand out because of their unique properties and low-cost and abundant nature. Their combination with different metals results in the enhancement of their innate properties. Metal-doped CDs have shown excellent results and competitive advantages in recent times. Considering the above useful critiques and CDs notable potentialities, this review discusses different approaches in detail to sense, adsorb, and photodegrade different pollutants in water samples. It was found that altering the electronic structure of CDs via metal doping has a great potential to enhance the optical, electrical, chemical, and magnetic capabilities of CDs, which in turn is beneficial for wastewater treatment.
环境受到家庭和工业排放物的污染是一个相关且持久的问题，需要新的解决方案。迫切需要创新的检测、吸附以及有毒成分的去除或原位降解方法。已经提出了各种有效的技术和材料来解决这个问题，其中碳点 (CDs) 因其独特的性质、低成本和丰富的性质而脱颖而出。它们与不同的金属结合会增强其固有特性。金属掺杂的 CDs 最近在这方面显示出了极好的效果和竞争优势。考虑到上述有用的评论和 CDs 的显著潜力，本综述详细讨论了不同的方法，用于检测、吸附和光降解水样中的不同污染物。结果发现，通过金属掺杂改变 CDs 的电子结构具有很大的潜力，可以增强 CDs 的光学、电学、化学和磁性能，这对废水处理是有益的。
