中文摘要 | ordered hexagonal mesoporous silica material (jlu-30) has been successfully synthesized in alkaline media at high temperature (> 160 degreesc, using cationic (1,3-dimethyl-2-imidazolidin-2-ylidene)hexadecylmethyl-ammonium bromide (dihab) as a template, and characterized with x-ray diffraction (xrd), transmission electron microscopy (tem), nitrogen adsorption-desorption isotherms, differential thermal analysis (dta), and thermogravimetric analysis (tg), as well as al-27 and si-29 nuclear magnetic resonance (nmr) spectroscopy. mesoporous jlu-30 shows much higher hydrothermal stability than mcm-41. si-29 nmr spectra indicate that the pore walls of jlu-30 samples synthesized at high temperature (160 degreesc) are fully condensed, giving a q(4)/q(3) ratio as high as 6.2. in contrast, mcm-41 synthesized at relatively low temperature (100 degreesc) shows the q(4)/q(3) + q(2) ratio at 1.1. such unique structural feature might be responsible for the observed highly hydrothermal stability of the mesoporous silica materials (jlu-30). |
