| Description |
The use of ultrasonic energy for chemical synthesis has recently become an interesting and growing area of research. Using this form of energy, we have synthesized nanoparticles of SnO(2) (8-30 nm) at room temperature by a sonication assisted precipitation technique. In order to understand the effect of ultrasonic energy on particle size and their distribution, the precipitation time was varied during the preparation. A sonication time of 3h was found to be optimum to produce SnO(2) nanoparticles having size below 10 nm. We found that a gradual increase of the sonication time gradually decreases the particle size with interesting morphology and increased surface area. The butane sensing properties of the synthesized powders exhibited a direct influence of the sonication time on the sensing properties. A 3h sonicated sample, exhibited a maximum response of around 98.88% towards 5000 ppm butane at 450 degrees C with a fast recovery time.
