Biosynthesis of SnO₂ nanoparticles by aqueous leaves extract of Aquilaria malaccensis (agarwood)

Abstract Biosynthesis of tin oxide nanoparticles (SnO 2 NPs) was cost-effectively carried out in non-toxic aqueous mixture Aquilaria malaccensis (agarwood) leaves extract and (IV) chloride pentahydrate solution at room temperature. The synthesized SnO NPs were characterized by using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive analysis (EDX) UV-visible diffuse reflectance (DRS). results from FT-IR spectra A. shows the presence functional groups polyphenolic bioactive compounds which act as template for reducing capping agents during synthesis activity. structural properties obtained are studied diffraction, indicates that crystallite size 6.3 3.4 nm sample fresh old respectively. morphology uniform distribution agglomerated spherical nanoparticles.
