The aim is to create carbon dot-modified ZnO-SnO2 nanocomposites for effective degradation of malachite green dye under sunlight.
Synthesize carbon dots using Moringa oleifera leaf extract and integrate with ZnO-SnO2 nanoparticles.
Characterize materials using techniques such as UV-vis spectroscopy and transmission electron microscopy.
Optimize photocatalytic conditions using response surface methodology.
Achieved 99% malachite green dye removal under optimal conditions of 10 mg/L dye concentration, 110 mg photocatalyst dose, and 100 min irradiation time.
Predicted degradation efficiency of approximately 97% based on response surface methodology model.
