A series of copper/MCM-48 mesoporous samples is prepared and characterized following two methods: atraditional hydrothermal synthesis and an impregnation with Cu(AcAc)2 before eliminating the structure-directing agent. The samples are characterized by XRD, BET, FTIR, TPR and TEM. Only for certaincases the morphological aspects of MCM-48 are not modified by the incorporation of copper into themesoporous framework. The samples are tested as catalysts for the liquid phase hydrogenation of cinnamaldehydein a Batch reactor, employing H2 as the reductant. Some Cu/MCM-48 catalysts were moreselective than copper supported on alumina (Cu/c-Al2O3) tested under the same reaction conditions.The reason for the better catalytic performance would be that copper is finely dispersed and highlyuncoordinated.
