Safe way to make zinc oxide nanorods

News

A non-toxic and environmentally friendly way to make nanorods of zinc oxide has been developed for the first time by researchers in Saudi Arabia.

The approach developed by researchers at King Khalid University and King Abdul-Aziz University could allow the nanorods to be used safely in biomedical and other applications.

The team demonstrated that it can synthesise zinc oxide nanorods with a simple reaction of water and zinc powder at a relatively low temperature.

The zinc powder is added to water, blasted with ultrasound for a few minutes and then warmed at a temperature of 200ºC for 24 hours.

After using X-ray and field emission electron microscopy to reveal the structure of the product, the researchers found that they could produce uniform nanorods of 30nm to 100nm.

Researcher M A Shah of King Khalid University said that his team’s approach is suitable for the large-scale production of a variety of zinc oxide nanostructures.
