摘要:	摘要： Highly ordered cubic mesoporous silicas MCM‐48 and Al‐MCM‐48 with high surface areas were successfully synthesized using Gemini surfactant as template under basic conditions within a very short time period with the aid of ultrasonic irradiation. The introduction of ultrasonic irradiation as an intermediate synthesis step before the hydrothermal treatment has reduced the total synthesis time significantly from 7 days to 24 hours, which is much shorter than the required time for the conventional synthesis of MCM‐48 directly via the hydrothermal route alone. The structural and textural properties of the resultant materials can be finely tuned by varying the ultrasonic irradiation time for pure MCM‐48 and Al‐MCM‐48 with various Si/Al ratios. The final products exhibited well ordered cubic Ia3d mesostructure with surface areas in the range of 968‐1861 m2g−1, pore volumes of 0.52‐0.91 cm3g−1, and pore diameters in the range of 1.9‐2.9 nm, which are comparable to the conventional analogues. Well‐ordered mesoporous silicas MCM‐48 and Al‐MCM‐48 with Ia3d bicontinuous and gyroidal cubic structure have been successfully synthesized within 24 hours via ultrasonic assisted hydrothermal approach under basic conditions using Gemini surfactant GEM 16‐12‐16 as the structure‐directing agent. The use of ultrasonic irradiation has reduced the total synthesis time significantly compared to the conventional hydrothermal process that takes at least 7 days to prepare MCM‐48. 其他題名： Jnl Chinese Chemical Soc 出版者： Weinheim: WILEY-VCH Verlag 出版日期： 2013-07 出處： Journal of the Chinese Chemical Society (Taipei), 2013-07, Vol.60 (7), p.831-838 版權： Copyright © 2013 The Chemical Society Located in Taipei & Wiley‐VCH Verlag GmbH & Co.
