Copper modified MCM-41 silica and AlMCM-41 materials obtained by various preparation techniques: direct synthesis, impregnation (ROT), cation exchange (IE) and template ionic exchange (TIE). Two fundamental characteristics of the materials prepared have been considered: (i) structure and texture, (ii) copper content and state. The results shows that the TIE method allow to obtain the best ordered materials with higher contain of copper.
