Synthesis, Structural Investigation, and Some Applications of Nickel Doped Tin Oxide Nanoparticles
- In this project, tin oxide nanoparticles and nickel doped tin oxide nanoparticles were prepared from tin II chloride by using co-precipitation and hydrothermal method. By using the Debye Scherrer equation, the average crystallite size of the tin oxide nanoparticles was found to be 33.53 nm by using co precipitation method at 500°C and 27.55 nm by using hydrothermal method. It was found that the crystal structure of tin oxide is tetragonal structure. The average crystallite size of the nickel doped tin oxide nanoparticles was found to be 19.44 (1%), 23.57nm(2%), and 33.47nm (5%) respectively. The morphology of SnO2 and Ni doped SnO2 nanoparticles showed spherical shape by FE SEM. Application of tin oxide and nickel doped tin oxide nanoparticles were done for adsorption properties and antimicrobial activities in this study. Antimicrobial activity on the tin oxide and nickel doped tin oxide nanoparticles were performed against six microbial strains Bacillus subtilis (N.C.T.C-8236), Staphylococcus aureus (N.C.P.C-6371), Pseudomonas aeruginosa (1679). Bacillus pumilus (N.C. I.B-8982), Candida albicans. and E coli (N.C.I.B-8134). It was observed that the highest antimicrobial activity of nickel doped tin oxide nanoparticles was found to be 45 mm on E coli strain by using agar well diffusion method. Characteristic of tin oxide and nickel doped tin oxide nanoparticles was investigated for gas sensor application by using ammonia.
