Aluminiumoxid enthaltender Feststoff mit großer Oberfläche

摘要

A solid (I) containing aluminIum oxide (Al2O3) is claimed, which is obtained by a process comprising contacting Al2O3 precursor(s) (II) with template compound(s) in a liquid medium, in which the template is a dendrimeric molecular nano-system (III) or mixture of 2 or more of these. Also claimed are: (i) the method of producing (I) in this way; and (ii) the use of (III) as template in the production of (I). Preferably The nano-system contains a nitrogen (N), phosphorus (P) or carbon (C) atom or a mixture of 2 or more of these as branch point. (I) also contains element(s) selected from sodium, potassium, calcium, magnesium, beryllium, boron, gallium, indium, silicon, germanium, tin, lead, bismuth, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, rhenium, iron, cobalt, nickel, ruthenium, copper, zinc, cadmium, mercury and cerium.
