<p>The invention relates to a material which, once calcined and in the anhydrous state, has general formula x (M1/nXO2): z ZO2: y GeO2: (1-y) SiO2, wherein x has a value of less than 0.2, preferably less than 0.15, and can equal zero; z has a value of between 0 and 0.1, preferably between 0 and 0.05; y has a value of between 0 and 1, preferably between 0 and 0.75; M represents one or more +n-charged inorganic cations; X represents one or more +3 oxidation state chemical elements (Al, B, Ga, Fe); and Z represents one or more +4 oxidation state cations different from silicon and germanium, preferably Ti or Sn. Said material can be used as a component of catalysts in acid catalysis processes or as a metal or oxide support in separation and absorption/adsorption processes.</p> |
