In situ templated sol-gel method has been adopted with simple EDTA ethylenediamine tetra aceticacid and ethylenediamine molecules to prepare gamma-Al2-xMxO3 +/- y, (M = Cu and or Ce). Above meso-macro porous materials were characterized by structural, spectroscopy, microscopy and textural techniques. Detailed characterization indicates that Cu2+ ions are introduced into the ceria and alumina lattice positions. Nano composite nature of the gamma-Al2-xMxO3 +/- y has been confirmed by detailed microscopy investigations. Catalytic activity of the above nanocomposite materials have been screened for environmentally important CO oxidation reaction. 30% Ce-60% Al and 10% Cu containing material shows the best activity among other meso-nnacroporous material with (50%) 100% CO oxidation at (107 degrees C) 145 degrees C.10aAlumina10aCO oxidation10aheterogeneous catalysis10aMeso-Macroporous Material10aNanocomposite10aSol-gel synthesis1 aGnanakumar, Edwin, S.1 aJohn, Jino, C.1 aRaja, Thirumalaiswamy1 aGopinath, Chinnakonda, S.  uhttps://library.ncl.res.in/content/functional-and-disordered-meso-macroporous-gamma-al2-xmxo3-y-m-cu-andor-ce-0
