In this work, spherical Sn and SnO 2 nanoparticles smaller than 5 and 20 nm, respectively, were synthesized using pulsed plasma in deionized water, simply and environmentally friendly. The tetragonal Sn nanoparticles showed good crystallinity and slight increase in lattice parameters. Thermo‐gravimetric analysis revealed insignificant weight loss from the particles, indicating their thermal stability up to 500 °C. The Sn nanoparticles then were annealed at 800 °C; in result, cassiterite phase of SnO 2 nanoparticles were successfully obtained. Structural and morphological analysis indicated the full oxidation of Sn and size growth of SnO 2 nanoparticles upto 20–25 nm. The SnO 2 nanoparticles showed good photocatalytic activity in degradation of organic dyes, such as methylene blue and methyl orange.
