Abstract

In this study, the effect of COPPER CHROMITE (CuO.Cr2O3) nanoparticles and multi-walled carbon nanotubes (MWCNTs) as NANOCATALYSTs on the thermal decomposition behavior of AMMONIUM PERCHLORATE (AP) has been investigated using Differential Scanning Calorimetry (DSC). At first, COPPER CHROMITE (CuO.Cr2O3) nanoparticles were prepared by INVERSE CO-PRECIPITATION method. In this method, cupric nitrate trihydrate (Cu(NO3)2.3H2O), and chromium nitrate nona hydrate (Cr(NO3)3.9H2O) with a mole ratio of 1:2 were used. Then, multi-walled carbon nanotubes were modified by a chemical method.The MWCNTs were used with the average approximate diameter of nanotubes varying from 20 to 30 nm and their lengths from 5 to 10 mm. Phase was studied by X-ray Diffraction Spectroscopy (XRD) and the obtained bonds via two methods of Fourier Transform Infrared Spectroscopy (FT-IR) and Raman Spectroscopy. Microstructure observations and size of nanoparticles were determined by Field Emission Scanning Electron Microscopy (FE-SEM). The average crystallite size of obtained COPPER CHROMITE was 18 nm. The results showed that using 3 wt.-% nano catalysts lowered the decomposition temperature of AP to 94.86 oC and 83.5 oC for COPPER CHROMITE (CuO.Cr2O3) and nano- MWCNTs, respectively. Meanwhile, the total enthalpies, for these two cases, were 1132.31 J g -1 and 1308.71 J g -1 respectively.
