Краткое описание

A nanocomposite with Al nanoparticles (~ 80 nm) embedded as the internal core and Cr2O3 and ETN nanoparticles (~ 10 nm) compactly coated on its surface was prepared via a sol-gel-freeze drying method. The effects of the initial concentration of CrCl3 (C0), solvent, and amount of propylene oxide (V3+PO/Cr) on the fabrication were discussed in detail, and the optimum technology was obtained. SEM, XPS, and IR analyses were employed to study the micron morphology, surface elements, and structure of the nanocomposite. Thermal analysis was also conducted with DSC-IR technology. The thermal decomposition gas products of the nanocomposite were detected and recorded as dynamic IR data as a function of the elapsed time. From the IR spectra collected at different times, the main gas product was determined to be NO2, which was simultaneously accompanied by CO2, CH2O, CH2, and CH fragments.
