【 摘 要 】

AgAl2O3 nanocomposite were synthesized by solution combustionTechnique using ammonium carbonate as a new fuel undersimultaneous combustion of alumina and silver particles condition.Samples prepared with different amount of silver, werecharacterized by XRD, BET, SEM and optical Absorptionmeasurements. XRD analysis was used to determine the change inphase and size of the synthesized nanoparticle with adding silver.BET analysis showed that added silver reduced specific surface butwhich is still suitable for catalytic application. BJH analysisshowed that pores in Ag/Al2O3 nano composite are mesoporous andin Al2O3 nano particles is microporous. TEM and SEM showedthat silver was distributed completely homogenously in pores ofAlumina, and didn’t change in surface of Alumina. Opticaltransmission showed the different existence of different Ag species.
