Abstract

CuO/ZnO/Al2O3 nanocatalysts were synthesized by microwave assisted combustion synthesis method using modified fuels containing ammonium nitrate as combustion aid. Sorbitol, propylene glycol, glycerol, diethylene glycol and ethylene glycol were used as combustion fuels to study fuel effect in MWCS method. The prepared nanocatalysts have been characterized by XRD, FESEM, EDX, FTIR and surface area analysis, BET techniques. The results show that combustion fuel can alter structural properties of fabricated nanopowder such as crystallography, dispersion and size distribution which can improve catalytic performance of synthesized nanocatalyst. FESEM images revealed that ethylene glycol resulted in better catalytic performance, since it has homogenous morphology with smaller particle size, high dispersion of metal oxides with no agglomeration.
