A series of MoO3-ZrO2 composite oxide catalysts were prepared by coprecipitation and impregnation methods and characterized by XRD, Raman, UV-Vis, TEM and sorptometric techniques. Characterization studies indicated the presence of tetragonal zirconia phase and well dispersed MoO3 species as isolated and polymolybdate clusters in the composite oxide. The MoO3(20 mol%)-ZrO2 material was used as efficient catalyst for synthesis of amidoalkyl naphthols under solvent free conditions using conventional as well as microwave heating. The results obtained clearly showed that the composite oxide catalyst was recyclable and highly efficient for the reaction giving good yield and purity of the products.(C) 2011 Elsevier B.V.
