Microstructure-Modulated Antibacterial Performance of Chemically Precipitated SnO2 Nanoparticles [PDF]
Journal of Applied Sciences and Nanotechnology, 2023 Tin oxide (SnO2) nanoparticles were synthesized via a facile chemical precipitation route using tin chloride (SnCl2•2H2O) as precursor and ammonia as precipitant. The as-synthesized nanoparticles were subjected to post-calcination at 300°C, 400°C and 500°
