Abstract

ABSTRACT Mesoporous SBA-15 has been synthesised using a binary acid H2SO4 as media. The effects of H2SO4 concentration and synthesis temperature on the morphologies and mesostructures of the obtained mesoporous SBA-15 materials were studied. The results revealed that the more-ordered structure was obtained at a H2SO4 concentration of 2 M, while a higher H2SO4 concentration of 3 M led to a less-ordered structure. In addition, with increasing H2SO4 concentration from 1 to 3 M, the morphologies of SBA-15 particles transferred from rod-like to sphere-like. This work demonstrated that mesoporous SBA-15 with various textural properties and morphologies can be feasibly obtained by controlling the H2SO4 concentration and synthesis temperature.

H2SO4可控合成介孔SBA-15

摘要以二元酸H2SO4为介质合成了介孔SBA-15。研究了H2SO4浓度和合成温度对所得介孔SBA-15材料形貌和介孔结构的影响。结果表明，在2M的H2SO4浓度下获得了更有序的结构，而在3M的较高H2SO4浓度导致了不太有序的结构。此外，随着H2SO4浓度从1M增加到3M，SBA-15颗粒的形貌从棒状转变为球形。本工作表明，通过控制H2SO4的浓度和合成温度，可以获得具有各种织构和形貌的介孔SBA-15。

期刊介绍： Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
