Physicochemical and textural properties of amino-functionalised mesoporous silica nanomaterials from different silica sources

In the study, we provided an insight into the nature of interaction that occurred at nanoscale level when preparing mesoporous nanomaterials with molecular scale cavity using either calcination or solvent extraction to remove the surfactant, improve the stability and suitability to surface functionalisation. By carrying out essential material characterisations, we were able to provide plausible empirical data and mechanism to support the morphological changes in the resulting mesoporous silica nanomaterials prepared from the two silica sources.

本研究揭示了在利用煅烧或溶剂萃取去除表面活性剂，以分子尺度腔体制备介孔纳米材料的过程中，纳米尺度层面的相互作用本质。通过进行关键材料表征，我们得以提供合理的实证数据和机制，以支持由两种二氧化硅来源制备的介孔二氧化硅纳米材料中形态变化。
