The invention relates to novel microporous crystalline aluminophosphate materials comprising Ti (TAPOs) based on gels containing Ti in a state of oxidation lower than (IV), preferably Ti(III). The invention also relates to the method for producing said materials. The resulting TAPO materials can comprise two types of cores, both non-described in aluminium phosphates, depending on the atmosphere to which they are exposed following the production thereof. In this way, if they are kept in the absence of oxygen, aluminophosphates will be produced, comprising Ti(III) (Ti(III) APOs) with redox properties for exploiting in catalysis, for example, in the production of plastics. The invention further relates to the first TAPO materials that do not contain Brönsted acid cores coexisting with the redox cores. On the other hand, if they are exposed to molecular oxygen, TAPO materials comprising Ti(IV) (Ti( IV) APOs ) are produced, but with an environment different from that of the known TAPOs in that, instead of Ti(OA1)4 o Ti (OA1)4-n (OTi)n (con 04, and therefore with a specific catalytic behaviour in acid and oxidation reactions. |
