Iranian and German scientists develop high-purity alumina nanoparticles

The scientists at the Isfahan University of Technology in Iran association with their colleagues from Germany have developed high-purity alumina nanoparticles using a green laboratorial method. Alumina nanoparticles are largely used in oil refinery for controlling the emission of greenhouse gases.

Alumina, a ceramic, is widely used in many industrial sectors due to its reasonable production cost and a host of versatile physical and chemical properties. Alumina has good thermal stability, high specific area, high surface acidity, and noticeable interaction with metals, and finds use in petrochemical and oil refinery processes as sorbent in adsorption and catalyst. It is very important to invent new and efficient methods to produce oxide nanoparticles such as alumina.

According to Iran Nanotechnology Initiative Council (INIC), the research was aimed at producing alumina nanoparticles by using purified raw materials. The reaction occurs at low temperature in a short duration of period. The production cost in this process is much lower than in other similar ones. The environmental pollution level is also reasonably low.

This study attempts to optimize final properties of the alumina nanoparticle, including their specific area, by using precursor with high purity and creating optimized production conditions.

Results of the research have been published in Dalton Transactions. The article has been financially supported by Iranian National Science Foundation.
