Abstract
Iridium catalyst was prepared using a novel titanium oxide-CMK-3 support synthesized
as a replica of Ti-SBA-15. The catalyst was applied in the hydrodenitrogenation of indole.
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
