The catalyst was applied in the hydrodenitrogena tion of indole. The activity was compared with an iridium catalyst supported over a grafted titanium-CMK-3. Struc tural and textural characterization of the catalysts was per formed 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 hydro denitrogenation 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.pdfeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Heterogeneous CatalysisNanoparticlesMesoporous materialsHydrodenitrogenationinfo:eu-repo/semantics/articleLedesma, Brenda Cecilia; Juárez, Juliana María; Vallés, Verónica Alejandra; Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel.https://creativecommons.org/licenses/by-nc-nd/4.0/
