Applying Ho mogeneo us Precipitation for Synthesis and Phys icochemi cal Ch aracterization of Cu O/CeO۲/ Al۲O۳ and CuO/ZrO ۲/Al۲O۳ N anopowders

Alumina supporte d copper oxide compo sites are widely applie d in variet y of organic and inorganic catalyti c reactions such as CO, hydrocarbo n and alco hol oxidation as well as NOx and SO۲ reduction reactio ns [۱,۲]. I n this research, effect ZrO۲ and CeO۲ o n the physic ochemical properties o f two ternar y CuO/ZrO۲/Al۲O۳ and CuO/CeO۲/ Al۲O۳ composites were s tudied. Mate rials and m ethods:CuO/ ZrO۲/Al۲O۳ and CuO/CeO۲/Al۲O۳ composites were prepared by homogenous precipitation meth od from nitrate form o f consumed metals. Different analysis such as XRD, FESEM, FT-IR an d BET wer e carried out to describe their various characteri stics.
