Summary: Nitrogen- and oxygen-doped fluorescent carbon dots (NOFCDs) were prepared using a hydrothermal carbonization technique with aqueous ammonia and Garcinia mangostana plant extract as nitrogen and carbon sources, respectively. The synthesized NOFCDs were characterized using various microscopic and spectroscopic techniques. The study revealed that NOFCDs exhibited excitation-dependent fluorescent emission and absorption with the strongest emission peak at 405 nm when excited at 320 nm. The NOFCDs were spherical in shape with a particle size of 3.58 nm. The presence of nitrogen and oxygen doping on the NOFCDs' surface was confirmed through XPS, FTIR, and EDS investigations. Additionally, the NOFCDs showed excellent catalytic activity in the detoxification of methylene blue when treated with NaBH4. Overall, this research highlighted the potential of green-synthesized NOFCDs for catalytic and environmental remediation applications.
