Example 1. Synthesis of gallium oxide Ga2O3

For the synthesis of nanostructured materials, which are nanoparticles, nanofilms and nanowires proposed many methods that can be divided into two principal groups. First, obtain nanostructures of materials normal size, i.e. bulk materials. Second, obtaining nanostructures from molecular level.

Aluminum and Oxygen gas react to form Aluminum Oxide.

The main disadvantages of the known methods for the synthesis of metal oxides as follows:

Main application markets for aluminium oxide nanoparticles are in:

"Typically, the synthesis of oxide nanoparticles involves the slow reaction of a weak oxidizing agent, such as hydrogen peroxide, with dilute solutions of metal salts or complexes in both aqueous and non-aqueous solvent systems," said Dr. Thomas Sutto, NRL research chemist. "The rapid exothermic reaction of potassium superoxide with the salt solutions results in the formation of insoluble oxide or hydroxide nanoparticulates."

Scientists at the U.S. Naval Research Laboratory (NRL) Materials Science and Technology Division have developed a novel one-step process using, for the first time in these types of syntheses, potassium superoxide (KO2) to rapidly form oxide nanoparticles from simple salt solutions in water.

The invention solves the problem of efficient synthesis of compounds of metal oxides.

Recent applications include oil and gas aluminium drill pipelines. Application of aluminium oxide nanofluids in enhanced oil recovery (EOR) has also been increasing in the recent years. The ability of nanoparticles to alter certain factors in the formation and in oil properties can enhance recovery.

In order to demonstrate the broad scale applicability of this new method, oxide or hydroxide nanoparticles have been prepared from representative elements from across the periodic table to rapidly produce nanometer sized oxides or hydroxides. In addition to the elements converted to oxide nanoparticles in the above illustration, it has also been shown that oxide nanoparticles can be prepared from second and third row transition metals, and even semi-metals such as tin, bismuth, thallium and lead.

2.1 Synthesis of alumina nanoparticles

In this paper, microwave-assisted green chemistry has beenused for the synthesis of AlNP. A facile approach has beenreported using tea, coffee and triphala extracts, acting asreducing agents for the synthesis of AlNP of well-defineddimensions in bulk amount. This eliminates the need oftoxic chemicals for the synthesis of nanoparticles. Theformation of AlNP with the microwave-assistance usingthese plant extracts has proved to be very faster than anyother method. These nanoparticles which are synthesizedusing green chemistry can be used for a variety of applicationsin the future. As triphala extract has medicinalimportance, the results described here will also be usefulfor its biomedical applications.
