摘要 采用异丙醇铝为铝源,3.5代PAMAM为模板剂,通过油滴球过程合成了介孔γ-Al2O3微球。研究发现在所合成的氧化铝中,介孔相呈海绵状或蠕虫状随机分布的三维网络结构;其孔径主要分布在2~6nm之间,且合成的介孔氧化铝的比表面积可达340m^2/g以上。 Mesoporous spherical γ-alumina granules were prepared by an oil-drop process from aluminum isopropoxide with 3.5G PAMAM dendrimer as template. It was found that a sponge- or worm-like randomly three-dimensionally connected mesoporous network could be obtained. Its mean pore diameters vary between 2 and 6nm and its specific surface areas reached to above 340m^2/g.
