PHOTOCATALYTIC ACTIVITIES OF SYNTHESIZED TIN(IV) OXIDE NANOPARTICLES BY USING AQUEOUS EXTRACT OF CITRUS AURANTIFOLIA LEAVES
Abstract
- Citrus aurantifolia leaves aqueous extract was used to synthesize tin(IV) oxide nanoparticles utilizing a straightforward, environmentally friendly, and inexpensive approach. Aqueous leaves extract of C. aurantifolia was utilized as a reducing agent, while tin(II) chloride dihydrate was utilized as the starting material. SnO2 NPs were produced at 600 °C, according to an X-ray diffractogram (XRD) examination, and their crystallite size was 28.7 nm when they were made with an aqueous leaf extract. The distinctive peak of SnO2 was visible in the 450–790 cm-1 range according to the results of the FT IR investigation. SEM examination revealed SnO2 NPs with very minor agglomerations. The average crystallite size of SnO2 NPs was determined by TEM examination to be consistent with the XRD results. For the commercial dye, methyl violet, which serves as a representative organic dye pollutant, the produced SnO2 NPs demonstrated outstanding degrading efficiency. The ideal conditions for the photocatalytic degradation of 10 ppm of methyl violet were achieved using 0.5 g of SnO2 NPs in the sunlight for 8 h.
