本文报道了一种与 SBA-16 相关的新型含骨架铝介观结构二氧化硅的合成方法。采用硫酸铝和pH调节方法成功合成了该材料。通过 X 射线衍射和 77K 的 N2 吸附研究了这种新型材料的结构和孔隙率特性。通过 27 Al-MAS-NMR测定Al插入并通过100K下CO吸附的红外光谱监测酸度。
A novel SBA-16-related synthesis of mesostructured silica containing framework aluminum is reported here. This material was successfully synthesized using aluminum sulphate and the pH-adjusting method. The structural and porosity properties of this novel material were studied by X-ray diffraction and N2adsorption at 77K. The Al insertion was determined by27Al-MAS-NMR and the acidity was monitored by infrared spectroscopy of CO adsorption at 100K.
