Nanocrystalline yttria doped zirconia (YZ) were prepared by sol-gel method and characterized byXRD, SEM, EDX, TGA and XPS techniques. The XRD results indicated the formation highlycrystalline material with 2 to 4 nm in size. The tetragonal phase of the nanoparticles was confirmed byXRD analysis. Small amount of this catalysts was efficiently catalyzed acetylation of benzyl alcoholwith acetic anhydride in short time under solvent free conditions. The 5 wt.% YZ gave best results at120 ºC with 100% conversion of benzyl alcohol with 100% selectivity of the product. Differentparameters were studied for optimization of acetylation, which proved the catalysts has excellentactivity and can be used at large scale applications in industry.
