چکیده Ferric Cl-doped CQDs were reported as a photocatalyst which synthesized via a feasible hydrothermal method and characterized using various techniques such as HRTEM imaging, EDS, EDS mapping, XRD, XPS, PL, FTIR, and UV–Vis spectroscopies. The photocatalytic activity of monometallic Fe@ClCQDs was scrutinized toward the photoconversion of RhB dye from water. The photoconversion of RhB dye in the presence of 6 mg of photocatalyst and 25 µL H2O2 was impressive (89%) in 90 s. The efect of catalyst dosage, light intensity, pH, H2O2 concentration, and temperature on dye conversion was studied. The results of using diferent scavengers indicated that ˚ OH has an important role in photocatalytic conversion. More importantly, the photoactivity of monometallic Fe@ClCQDs remains>89% after eleven times, which shows their good stability and utility. Hence, the monometallic Fe@ClCQDs are promising photocatalysts for extraordinarily efcient dye conversion in an extremely short time.
