This paper describes the synthesis of ordered mesoporous silica MCM-41 and mesoporous stannosilicates Sn-MCM-41, under mild and non-hydrothermal conditions, as well as their characterization. The aim was to explore the influence of the synthesis temperature (25 and 80 °C) on the properties of the mesostructured material. A short synthesis time (30 min) and a sol-gel method were employed, with an Si/Sn ratio of 10, using tetraethyl orthosilicate (TEOS) as a source of silica and cetyltrimethyl ammonium bromide (CTAB) as a structure-template. To the best of our knowledge, this is the first time that sodium stannate (Na₂SnO₃) has been employed as an Sn(IV) source in MCM-41 synthesis. The characterization of the materials was performed via several techniques and the results revealed the formation of MCM-41 and Sn-MCM-41 with a high specific surface area and narrow pore size distribution, and there are strong indications that Sn(IV) is inserted in the MCM-41 lattice. This approach represents a significant advance compared to the materials commonly obtained via hydrothermal synthesis with time-consuming procedures and could be easily applied to large-scale production.

本文描述了在温和非水热条件下有序介孔二氧化硅MCM-41和介孔锡硅酸盐Sn-MCM-41的合成及其表征。目的是探索合成温度（25和80°C）对介孔结构材料性能的影响。使用原硅酸四乙酯（TEOS）作为二氧化硅源和十六烷基三甲基溴化铵（CTAB）作为结构模板，使用较短的合成时间（30分钟）和溶胶/凝胶法，Si / Sn比为10。据我们所知，这是锡酸钠（Na ₂ SnO ₃）已被用作MCM-41合成中的Sn（IV）源。通过几种技术对材料进行表征，结果表明形成了具有高比表面积和窄孔径分布的MCM-41和Sn-MCM-41，并且有很强的迹象表明已插入Sn（IV）在MCM-41晶格中。与通常通过耗时的程序通过水热合成获得的材料相比，该方法代表了重大进步，并且可以轻松地应用于大规模生产。
