In this paper, orthorhombic phase zirconium monosilicide nanomaterials have been successfully synthesized through a lithium thermal reduction in a stainless-steel autoclave at a low temperature of 600 0C. X-ray diffraction indicates that the obtained product is orthorhombic zirconium monosilicide. Scanning electron microscopy shows that the obtained zirconium monosilicide product consists of nanoparticles and nanorods. The oxidation resistance of the obtained zirconium monosilicide product is investigated.

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.

In this paper, we have successfully prepared porous chromium carbide ceramics by a facile one-step method. The synthesis reaction is carried out in an autoclave using waste polyethylene as a carbon source. Generally, the as-obtained chromium carbide is characterized by X-ray diffraction, scanning electron microscope (SEM) and transmission electron microscope. X-ray diffraction pattern shows that the as-obtained sample is cubic phase chromium carbide (Cr 23 C 6 ). The SEM results show that the sample is composed of porous particles with an average pore size of 200 nm. In addition, the oxidation resistance of the as-obtained Cr 23 C 6 sample was studied by thermogravimetric analyzer. The resource utilization of waste plastic can solve the problems of energy shortage and environment pollution simultaneously to achieve sustainable development.
