Quantitative 29 Si NMR spectroscopy of ordered mesoporous silicas: revisiting Q 3 / Q 4 ratios and surface hydroxylation in SBA-15 and MCM-41
Abstract
sites, challenging earlier assumptions about its surface hydroxylation. By employing advanced deconvolution techniques, the study offers a more accurate characterization of these materials, particularly in terms of their surface chemistry, rehydration behaviour, and functionalization potential. This revised understanding is crucial for improving predictions of material behaviour and for optimizing its use in applications such as catalysis and gas separation. The proposed method thus enables a rethinking of the properties of mesoporous materials, offering more profound insight into their structure-function relationships.
