Quantitative 29Si NMR spectroscopy of ordered mesoporous silicas: revisiting Q3/Q4 ratios and surface hydroxylation in SBA-15 and MCM-41.

This study highlights a method for analyzing the structural features of mesoporous silicates (MCM-41, MCM-48, SBA-15, and SBA-16) using 29Si NMR spectroscopy, with a focus on the distribution of Qn (n = 0-4) silicon environments. This approach not on…
