چکیده

In this paper, we report the first time preparation of SnO2 nanoparticles (NPs) using a green chemistry method. The leaf extract of Plectranthus amboinicus was used as reducing and stabilization agent for synthesizing SnO2 NPs. The synthesized SnO2 NPs were characterized by SEM, EDX, XRD and UV-vis spectroscopy. Results showed that the biosynthesized SnO2 NPs owing a high purity. The photocatalytic property of the biosynthesized SnO2 NPs was investigated by photodegradation of rhodamine B (Rh B) under visible light illumination. Results indicated that the photocatalytic performance of the biosynthesized SnO2 NPs is much higher than that of commercial SnO2. Moreover, the biosynthesized SnO2 also exhibited an excellent reusability.
