| 摘要 |
This invention is directed to a method for making metal-aluminum-oxide materials according to sol-gel techniques from particularly defined heterobimetallic alkoxides comprising bis[bis(2-propanolato)aluminum)-tetrakis( mu -(2-propanolato)]alkaline-earths and, optionally, tris [(bis(2-propanolato)aluminum)hexakis( mu -(2-propanolato))]-lanthanides, and the materials so made. The materials may be in varied forms like sols, gels, xerogels, and calcined materials.
