Synthesis of silicon carbide nanoplates by using laboratory wastes as resource at low temperature

Abstract

In this study, silicon carbide (SiC) nanoplates are prepared from the waste quart tube (main composition: silicon dioxide) and waste autoclave lining (main composition: polytetrafluoroethylene) produced in the laboratory. The reaction is carried in a stainless steel autoclave at 600 °C through a magnesium reduction route. Electron microscopy investigations show that the nanoplate thickness of the SiC sample is about 20 nm, and the edge length is about 200 nm. Furthermore, the photoluminescence property of the obtained SiC nanoplates is investigated.
