Abstract

Tin dioxide (SnO₂) nanoparticles were synthesized via a simple co-precipitation method using stannous chloride dihydrate (SnCl₂·2H₂O) as the precursor and ammonia as the precipitating agent, followed by the addition of activated charcoal and calcination at 600 °C. The morphological properties of the obtained nanoparticles were investigated by scanning electron microscopy (SEM). The SEM analysis revealed spherical grain morphology with an average particle size of approximately 21 nm and high crystallinity. The method employs low-cost starting materials and straightforward procedures, making it suitable for the preparation of nanostructured SnO₂ with potential applications in gas sensing and catalysis.

Keywords: SnO₂ nanoparticles; co-precipitation; scanning electron microscopy; nanocrystalline tin oxide
