Iranian researchers in association with their US and Malaysian colleagues acquired the technology to produce zinc oxide nanostructures through the simple sonochemical method.

Iranian Scientists Use Sonar Waves to Synthesize Zinc Oxide Nanostructures

Tehran, Iran | Posted on January 16th, 2013

Such structures are applicable in various industries such as nano-electronics, petroleum, and solar cells.

"In order to produce oxide nanostructures, the presence of an energy source is usually required," stated Dr. Ali Khorsand Zak, one of the researchers of the plan. "The required energy is produced by heat or by radiation through UV. In this research, it was tried to use sonar energy in order to synthesize zinc oxide nanostructures. This method is faster and more cost-effective in comparison with the majority of the existing methods to produce zinc oxide nanostructures, especially nanorods. Therefore, this product can be produced by using sonar energy in case there is no furnace, autoclave, or oven."

Chemicals required for the synthesis of zinc oxide include zinc acetate salt, sodium hydroxide, and ammonia solution, and the process does not need agents to control the structures or surfactants. This is a simple and green method because it does not need high temperature or very toxic chemicals. The final formation of zinc oxide nanostructures can be controlled by adjusting ultrasonic energy through creating changes in time of the ultrasonic waves.

"In this research, nanorods were produced with high ratio of length to diameter as well as flower-type structures. Nanorods can be used in electronics industry while nano flowers are applicable in the production of solar cells," Dr. Khorsand Zak continued.

Among the advantages of this method, mention can be made of the high quality of the product due to the control on the shape of the products, homogeneity and high purity.

Results of the research have been published in January 2013 in Ultrasonics Sonochemistry, vol. 20, issue 1, pp. 395-400.
