摘要

单分散SiO2微球广泛应用于催化、分离、吸附和药物传递等领域。它们的粒度、均匀性和比表面积对这些应用至关重要。本文报道了以十六烷基三甲基溴化铵为模板剂，十六烷基胺兼作扩孔剂和催化剂制备单分散SiO2微球的新方法。通过控制反应物的数量和反应条件，我们获得了单分散的SiO2微球，其粒径范围为800 nm至2.5 μm，具有非常大的比表面积。值得一提的是，在室温下制备出了粒径为2 μm且粒径分布极为均匀的微球。令人兴奋的是，它的BET比表面积为1543 m2/g。详细研究了影响微球制备的各种因素，并阐明了微球的生长机理。

Monodisperse Silica Microsphere with Extremely Large Specific Surface Area: Preparation and Characterization

Monodisperse SiO₂ microspheres are widely used in catalysis, separation, adsorption, and drug delivery. Their particle size, uniformity, and specific surface area are crucial for these applications. This study reports the novel preparation of monodisperse SiO₂ microspheres using cetyltrimethylammonium bromide as the template agent, employing hexadecylamine serving concurrently as a pore-expanding agent and catalyst. By controlling the reactant quantities and reaction conditions, we achieved monodisperse SiO₂ microspheres with tunable particle sizes ranging from 800 nm to 2.5 μm with exceptionally large specific surface areas. It is worth mentioning that microspheres with a particle size of 2 μm and extremely uniform size distribution were produced at room temperature. Excitingly, it has a BET specific surface area of 1543 m²/g. Various effects on the preparation of the microspheres were investigated in detail, and the growth mechanism of these microspheres was elucidated.
