Description :
Magnesium aluminates, MgAl2O4, have been synthesized by solution combustion synthesis
method using oxalyldihydrazide as a fuel and corresponding metal nitrates as oxidizer. It has been
characterized by XRD, BET surface area and powder density measurements. Surface area has been
measured by BET method and has a value of 12.67 m2 g-1. Particle size was calculated by using
values of surface area and powder density, which has a value of 71 nm. The MgAl2O4 powders thus
synthesised have been used as a catalyst for the decomposition of H2O2 at two different temperatures.
Activation energy has been found to be 299 Cal.mol-1 suggesting chemisorption is taking place.
