摘　　要：本文以溶胶 凝胶法自正硅酸乙酯和硝酸铝制备纳米莫来石,并将其应用于蒽醌加氢制取双氧水的反应中,考察其催化性能,得出了纳米莫来石在催化加氢上有一定的应用前景,并对反应机理作了初步探讨。Nanometergrade mullite powder was synthesized by solgel process from tetraethoxysilane(TEOS) and aluminum nitrate and used in anthraquinone hydrogenation to hydrogen peroxide. Activity of the catalyst was studied by means of TPR, XRD and TEM. Reaction mechanism over nanometergrade mullite were discussed, too.
