Facile One-Pot Decoration of SnO2 Quantum Dots on the Surface of the Iron Phosphate Nanosheets for Enhanced Catalytic Decolorization of Methylene Blue Dye in the Presence of NaBH4

Herein, a SnO2 quantum dots (SQDs) @ FePO4 nanosheets (FPNSs) was prepared by a simple procedure without additional instruments and characterized using XRD, FTIR, SEM, and TEM. SQD@FPNSs nanocomposite (FP-Sn) exhibited improved catalytic activity for the degradation of methylene blue (MB). Approximately 92% of the MB was successfully decolorized within 6 min using FP-Sn in the presence of NaBH4.
