Formation mechanisms and fluorescence properties of carbon dots in coal burning dust from coal fired power plants [PDF]
Advanced Photonics Research 5(10), 2400010 (2024)Carbon dots (CDs) shows great application potential with their unique and excellent performances. Coal and its derivatives are rich in aromatic ring structure, which is suitable for preparing CDs in microstructure. Coal burning dust from coal-fired power plants can be utilized as a rich resource to separate and extract CDs.
