Novel layered organic-inorganic hybrid materials consist of molybdenum oxide have been synthesized using three aminohydroxy ligands; diethylenetriamine, 2-(2-aminoethoxy) ethanol and 2-(2-aminoethylamino) ethanol. Different analysis methods have been utilized for understanding of the bonding nature between the organic and inorganic components and how the insertion of organic groups affects the structure of the inorganic layers (MoO3). Moreover, the influence of these different structures on the catalytic performance of oxide is discussed. The coordination of organic molecules to molybdenum center shows a decrease in the Mo=O bond strength, as might be characteristic in catalytic reaction. Furthermore, fabrication of the organized nanoplatelets of molybdenum oxide is achieved by calcinations of these hybrid materials at 600 °C. Somewhat oriented nanoplatelets are viewed with different catalytic activity according to their surface areas. The higher intercalated material shows higher surface area in its calcined material.
