Abstract

Nanocryslalline metal aluminates MAl2O4, M=Mn, Cu and Zn have been prepared by the combustion of aqueous solutions containing corresponding metal acetate, aluminium nitrate, ammonium nitrate and different fuels, e.g., urea/carbohydrazide/oxalyldihydrazide I/hexamethylenetramine/glycine, The spinels obtained are nanosize (10-80 nm) oxides with surface area varying from 40 to 180 m(2)/g depending upon the fuel used. The products have been characterised by powder XRD and Al-27 MAS NMR spectroscopy. The particulate and morphological properties have been investigated using TEM and SEM techniques. Both ZnAl2O4 and CuAl2O4, prepared with carbohydlazide and glycine furls ale porous
