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 nitra...
NiCr2O4 normal spinel nanostructures were prepared via hydrothermal treatment at 180 °C for 12 h in the presence of cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulphate (SDS) and poly vinylpyrrolidone-25000 (PVP-25000) as capping agents and subsequent calcination process at 500 °C for 3 h . In this method, [Ni(en)2(H2O)...
