Scientists have developed a new way to convert silicon into nanoparticles




An ecologically pure method of silicon-to-nanoparticles conversion has been developed by a group of scientists. This was reported on August 28 by ACS Sustainable Chemistry & Engineering, a weekly peer-reviewed scientific journal published by the American Chemical Society.





The method allows for recycling faulty silicon solar panels into silicon nanoparticles of a fixed size. The researchers have selected temperature, hydrolysis time, and acidity.

They used ammonia as a catalyst. The method allows recycling silicon wafers with different micro additives into nanoparticles with an average diameter of 50 nanometers. The work was performed by Skoltekh scientists together with their colleagues from Moscow State University.

It should be reminded that silicon is one of the most widespread elements on Earth. Its content of silicon in the Earth's crust is about 28% by mass.

It is widely used in modern electronics since it is a semiconductor in monocrystalline form. Silicon oxide is used in construction as quartz sand. Its nanoparticles can be used as an inert and non-toxic carrier.
