Abstract: Bimetallic nanocrystals, viz., Cu-Co, Cu-Fe and Cu-Zn, have been prepared by hydrazine reduction in ethylene glycol and characterized by X-ray diffraction, transmission electron microscopy and energy dispersive X-ray analysis. The particle size of the nanocrystals is found to be of the order of 10-38 nm. These nanocrystals have been found to have a significant catalytic effect on the thermal decomposition of ammonium perchlorate and also on the burning rate of composite solid propellants. The catalytic characteristics have been attributed to the large surface area and the active chemical nature of the bimetallic nanocrystals.
