Synthesis and Characterization of Cu(Ⅱ)-contained MCM41 with High Content of Copper

Abstract

Abstract: A series of Cu-containing MCM41 with high contents of copper was synthesized at room temperature by using Na₂SiO₃ as Si sources and Cu(NH₃)₄(NO₃)₂ as Cu sources and cetyltrimethyl ammonium bromide(CTAB) as the template. The influence of reaction conditions such as time, temperature, pH value and copper contents upon the structure of the materials was systematically studied. The mesoporous material containing up to 26%(mass fraction) copper was successfully synthesized under the best reaction conditions(t=20 ℃; pH=9—10; t=72 h). The structure of the materials was characterized by XRD, HRTEM, BET, TG-DTA, FTIR, ICP and XPS. The obtained material has a high surface area of 525 m²/g with a narrow pore distribution at 3.11 nm.
