摘要：
3C-SiC nanowires have been synthesized by reaction of poly(ethylene terephthalate)(PET) waste with SiO2 microspheres in supercritical carbon dioxide system at 650 degrees C for 3 h, followed by vacuum annealing at 1500 degrees C for 4 h. The product was characterized by X-ray diffraction, Raman spectroscopic, Field Emission Scanning Electron Microscopy, and High-resolution Electron Microscopy. The 3C-SiC nanowires are tens of microns in length and 30-150 nm in diameter. It is found that the reaction forming 3C-SiC nanowires take place in the inner of the carbon microspheres generated from PET. The formation mechanism of the 3C-SiC nanowires was discussed.
