Iridium catalyst was prepared using a novel titanium oxide-CMK-3 support synthesized as a replica of Ti-SBA-15. The catalyst wasapplied in the hydrodenitrogenationofindole. The activity was compared with an iridium catalyst supported over a grafted titanium-CMK-3. Structural and textural characterization of the catalysts was performed by means of N2 adsorption, XRD, UV?Vis?DRS, Raman spectroscopy, XPS, TEM and H2 Chemisorption. Ir-Ti-CMK-3 was the most active catalyst for the hydrodenitrogenation reaction at mild conditions. Titanium oxide contained in carbon ordered mesoporous CMK-3 promotes a very good anchorage of iridium metallic clusters in the carbon framework reaching high active site distribution and more stable nanoclusters.
