Paper Title:
The Preparation of Fibrous MCM-41 Using Microwave Heating
  Abstract

Mesoporous MCM-41 materials were prepared using the conventional thermal and microwave heating method. Both in conventional thermal and microwave heating synthesis of MCM-41, tetraethyl orthosilicate (TEOS) and cetyltrimethyl ammonium bromide (CTAB) were used as Si source and template, respectively. Microwave heating was carried out in a modified 400 W, 2.45 GHz microwave oven. In both methods, the crystallization temperatures was 70 °C and crystallization time was 3~12 h. The prepared MCM-41 samples were characterized by XRD, TEM and SEM. The XRD patterns of MCM-41 samples prepared from both the methods were typical of a relatively well ordered material. TEM results also revealed that the MCM-41 samples prepared from both the methods possess the regular hexagonal array of mesoporous channels. On the contrary, SEM has shown the difference in morphologies of the MCM-41 samples prepared from both the methods. The samples prepared by conventional thermal heating method mainly consist of irregular and small particles, whereas the samples prepared by microwave heating method have elongated rope-like structure and their length extends longer than 10 μm.
