    • Abstract

       

      The novel route of synthesis and catalytic performance of nano-sized Silicalite-1 are presented. Nano-sized Silicalite-1 was initially obtained from a clear solution using sodium silicate as silica source and tetrapropylamonium hydroxide as a template. The effects of silica source on the product yield, purity, crystallization rate and crystallinity were investigated. Effect of seeds in the synthesis was also studied. Nucleation time decreased to6hfrom24husing 4% seed, with yield and crystallinity 70% and 90%, respectively. The catalyst was characterized by XRD, FE-SEM, TG, FITR and N2 adsorption–desorption techniques. Transition metals like Fe, Cu and Mo were impregnated by wet impregnation method. Cu-impregnated nanosized Silicalite-1 was found to be highly active for the oxidation of toluene with H2O2.
