ABSTRACT

Transition metal nanoalloys of 3d-series (Zn-Cu, Zn-Fe, and Zn-Ni) were prepared by hydrazine reduction of metal chloride in ethylene glycol at 60°C and characterized by Scanning electron microscopy (SEM) and X-ray diffraction (XRD). XRD pattern gave average particle size for Zn-Cu, Zn-Fe, and Zn-Ni as 16, 80, and 44 nm, respectively. The effect of TMNs on the thermal decomposition of ammonium perchlorate (AP) was investigated using Thermogramatery (TG), Differential scanning calorimetery (DSC) studies. DSC with three different heating rates was used to evaluate activation energy of high-temperature decomposition by Kissinger equation. Zn-Cu was found to be best.
