The Synthesis of Mesoporous Molecular Sieve MCM-41 in Glycerol System

Abstract

An efficient method for mesoporous molecular sieve MCM-41 was introduced in this report. In EDA/TEOS/CTAB/glycerol system, mesoporous molecular sieve MCM-41 has been synthesized at room temperature and under hydrothermal condition, respectively, characterized by X-ray power diffraction and N2 adsorption. Compared with the samples synthesized under hydrothermal condition, the samples synthesized at room temperature have better order, larger pore diameter and narrower pore diameter distribution.

Effect of MCM-41 nanoparticles on ARGET ATRP of styrene: Investigating thermal properties

“…A sharp and intense peak around the diffraction angle of 2.5 and also some low intensity peaks in diffraction angles of 3-5 can be ascribed to the hexagonal structure of the synthesized MCM-41 nanoparticles. 35,36 Nitrogen adsorption/desorption isotherm of the calcined MCM-41 nanoparticles is presented in Figure 2. During nitrogen physisorption experiment, the synthesized sample reveals mesoporous materials behavior and shows IV isotherm according to the IUPAC classification.…”

“…(iii) A long plateau at higher pressures due to the low adsorption of N 2 on the external surface of calcined MCM-41 nanoparticles (saturation step). 35,36 Table 2 summarizes extracted data from the nitrogen adsorption/desorption isotherm.…”
