Green synthesis of ZnCo.sub.2O.sub.4 nanoparticles by Aloe albiflora extract and its application as catalyst on the thermal decomposition of ammonium perchlorate

ZnCo.sub.2O.sub.4 nanoparticles were prepared by green method using Aloe albiflora extract solution and characterized by Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy, and the result showed that the average particle size was
