Abstract (en)

[origin: WO2006018545A2] The invention relates to a method for preparing a mesoporous boron nitride having a homogeneous and ordered porosity and a high specific surface area consisting a) in impregnating a mesoporous mould which is provided with a homogeneous and ordered porosity and has a high specific surface area with a boron nitride precursor, b) in carrying out ceramisation by means of the precursor thermal decomposition in such a way that a boron nitride is formed and c) in removing the thus produced boron nitrides from the mould.
