Silica mesoporous molecular sieves have specific advantages, including ease of preparation, low cost, excellent thermal and chemical stability, large internal surface area and high concentration of surface Si–OH groups. MCM-41 is member of mesoporous molecular sieves with hierarchical structure and hexagonally packed arrays that can be used as catalyst supports [1–3] . In the present work, we report synthesis of new zirconium complex supported on mesoporous silica by anchoring of adenine on the wall of functionalized MCM-41, then reacted with ZrOCl2. The resultant MCM-41-Adenine-Zr was characterized by FT-IR, XRD, TEM, SEM, TGA, EDS, ICP and BET techniques. It was exhibited that the MCM-41-Adenine-Zr can be used as an efficient and thermally stable nanocatalyst forthe oxidation of sulfides.
