摘要：Mesoporous Zr-MCM-41 and Ti-MCM-41 have been synthesized at room temperature by sol-gelmethod using templates possessing high surface area, good thermal stability and maximum M4+ incorporation varyingSiO2:ZrO2/TiO2 ratios. The salient feature is synthesis of the materials at room temperature. Both the synthesizedmaterials have been characterized for elemental analysis by ICP-AES, XRD, TEM, SEM, EDX, surface area (by BETmethod), pore volume and pore distribution (BJH method), UV-DRS, FTIR and TGA. Further, the catalytic potential ofboth the materials have been compared by studying epoxidation as a model reaction using H2O2 as an oxidant in theconversion of allyl chloride to selectively produce epichlorohydrin in a single step at room temperature by varyingseveral parameters such as catalyst amount, reaction time, types of oxidants including catalyst regeneration and reuse.
