A green synthesis, characterization of highly luminescent carbon dots from Moringa oleifera gum application as an efficient potentiometric sensor for Hg2+ toxic metal ions

摘要

In this study, synthesis of highly luminescent carbon dots (CDs) is one of the hot research areas in the present-day context C-dots synthesis from Moringa oleifera gum is a green materials. The C-dots synthesis using hydrothermal method using 180 degrees C for 24 h reaction. We have synthesized highly luminescent CDs in a green way which can be adopted for large-scale production of luminescent CDs. In the newly synthesized C-dots characterizations including UV-Vis, FT-IR, Raman, PL and FE-SEM etc. The newly prepared CCPE was using C-dots and potentiometric heavy toxic metal ions sensing. We have demonstrated the CDs as a sensitive and selective potentiometric sensor for the determination of Hg2+ ions which is a well-known environmental toxic pollutant.
