Abstract: Tin oxide (SnO₂) nanoparticles are prepared by simple and cost-effective biosynthesis method, wherein, tin chloride (SnCl₄) reacts with Bengal gram bean (Cicer arietinum L.) extract. The assynthesized SnO₂ nanoparticles were coated onto the glass substrates using doctor blade method to form thin films. The films were further annealed at 250°C and used for characterization and gas sensing applications. Alternatively, the SnO₂ nanoparticles were biosynthesized using carbohydrate (starch) and also by chemical precipitation method. A comparative study of structural and morphological properties of chemical and biosynthesized SnO₂ nanoparticles is also carried out. Further, room temperature ammonia gas sensing properties of the biosynthesized SnO₂ nanoparticles thin films are studied.
