The contamination of the environment by domestic and industrial discharges is a persistent problem that requires innovative solutions. Carbon dots, particularly metal-doped carbon dots, have shown great potential in sensing, adsorbing, and photodegrading pollutants in water samples. This review highlights the importance of altering the electronic structure of carbon dots through metal doping to enhance their capabilities for wastewater treatment.
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.
