摘要：

We report here on the first one-pot synthesis of mesoporous silica SBA-16 containing aluminum. This material was successfully synthesised using poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) Pluronic F-127 (PEO106PPO70PEO106) as structure directing agent, butanol as co-surfactant and specifically adjusting the pH during the synthesis (i.e. adopting the so called "pH-adjusting method"). The structural and porosity properties of the novel [Al]-SBA-16 were studied by X-ray diffraction, Al-27-MAS-NMR and N-2 adsorption at 77 K. The acidity was monitored by infrared spectroscopy of CO adsorption at 100 K. (C) 2011 Elsevier Inc. All rights reserved.
