One of the main challenges of making Nano catalysts is choosing and preparing suitable modifiers. The present study reports the synthesis of carbon Nano dots by a low-cost hydrothermal method using Indigofera tinctoria leaf extract as a new carbon precursor. The optical properties of CQDs were analyzed by UV-visible spectroscopy and fluorescence studies. Surface morphology, functional groups and crystallization of CQDs were evaluated by HR-TEM, FT-IR and XRD methods, respectively. The spherical appearance of the synthesized CQDs was confirmed by HR-TEM, and the calculated size of the CQDs was 4 nm. XRD and SAED pattern results provide evidence for the amorphous nature of the prepared CQDs. The thermal stability of CQDs was investigated using TGA analysis. The obtained CQDs acted as a green Nano catalyst.
