New Low-Cost Method Offered for Synthesizing Tin Oxide Nanoparticles

An Inexpensive environmentally sustainable new method was presented by Iranian researchers to synthesize tin oxide nanoparticles.

Tin oxide (SnO2) is a very important type-N semiconductor with almost wide band gap energy (Eg=3.6 eV) at the room temperature which is used for making gas sensors, solar cells, etc.

The synthesis of this compound at nanoscale would provide new opportunities for discovering the changes in physical properties of this semiconductor. There have been proposed many methods for synthesizing SnO2 nanoparticles but they require high temperatures or long reaction times.

Mahdi Behboudnia, a lecturer at Urmia University of Technology, Iran, proposed a method to synthesize the nanoparticle which is not only economical, but also causes the least damage to the environment.

“In this study, we first mixed certain amounts of sodium hydroxide and an environmentally sustainable ionic liquid together. Then, while stirring the solution, we added some tin chloride to it,” he told INIC.

After being stirred, the solution was exposed to ultrasonic waves and centrifugation for a definite time to yield a white precipitation. Finally, we rinsed the precipitation with distilled water and ethanol each twice and dried it, Behboudnia said.

It is remarkable that the product was highly pure and quantitatively, qualitatively, and economically favorable compared to its counterparts. These nanoparticles could be also used for the removal of textile factories’ pollutants.
