以四甘醇（TEG）为模板剂，采用溶胶-凝胶法制备了介孔氧化铝tud1。研究了TEG和溶剂对最终产物孔隙结构的影响。提出了一种采用非表面活性剂模板的机理。经长时间高温热处理，发现tud1具有无定形骨架、高比表面积、大孔容、窄孔径分布等特点，具有较高的热稳定性，为其在吸附和催化等领域的应用奠定了基础。
Mesoporous alumina, TUD-1, was prepared via a sol-gel process by using tetraethylene glycol (TEG) as template. The effect of TEG and solvents on the pore structure of the final products was studied. A mechanism using non-surfactant template was proposed. It was found that TUD-1 has amorphous framework, high surface area, large pore volume and narrow pore size distribution together with high thermal stability upon prolonged heat treatment at high temperatures, which is essential for applications in adsorption and catalysis.
