modern water treatment by electrochemical oxidation

So, CDs can be used for water treatment.įor instance, CDs obtained from grass carp successfully detected mercury ions in lake water Further, they are also promising nano-fillers in fabricating thin-film nanocomposite membranes. Water Treatment: CDs contribute rich oxygen-containing moiety on their surface and are favourable for water solubility. Note: Organic pollutants in polluted water can act as electron and hole-transferring agents, while carbon dots act as photosensitiser.Ĭontaminant Adsorption: CDs can provide many surface adsorption sites due to their small size and large specific surface area. They also enable the detection of pollutants by changing colour. They are widely used as a fluorescent nanoprobe for pollutant detection because of their high fluorescence emission. So they are becoming more popular as candidates in applications like sensing and bioimaging. Pollutant Sensing: CDs are electron donors and acceptors. What are the potential applications of carbon dots (CD)? Read more: Carbon Markets: Benefits and Challenges – Explained, pointwise CDs are inexpensive, highly biocompatible, and environment-friendly. CDs possess remarkable optical properties, which differ peculiarly based on the precursor used for synthesis. CDs have the potential to be used instead of quantum dots, which are more toxic and less biocompatible.

CDs have garnered the attention of researchers mainly due to their convenient availability from both organic and inorganic materials. What are the advantages of carbon dots (CD)? Note: CDs have also been produced from water hyacinth waste. “Bottom-up” method: CDs are produced from carbonising small molecule precursors by pyrolysis, carbonisation, hydrothermal processes or microwave-assisted synthesis.

“Top-down” method: This approach converts large carbon structures into quantum-sized carbon dots by laser ablation, arc discharge, and chemical or electrochemical oxidation. The dots show continuous and broad absorption spectra, intense fluorescent activity, excellent photostability and highly tunable photoluminescence. They were discovered in 2004 and have an average diameter of less than 10 nanometres. About carbon dots (CD)ĬDs are one of the youngest members of the carbon nanomaterial family. What is the News?Īccording to scientists, modern technology like nanomaterials or carbon dots (CD) might be the solution to environmental issues like water pollution.
