Ti-CMK-3 carbon mesoporous was prepared using a novel synthesis method. This new method avoids the hard template synthesis, in order to reduce time and energy consumptionand cost. Structural and textural characterization of the catalyst was performed by N2 adsorption, XRD, UV?Vis?DRS, Raman spectroscopy and TEM. The characterization results indicated that the textural and structural properties of the material synthesized by the short time method are comparable with the properties of the material prepared by the hard template method. Ir-Ti-CMK-3 catalyst obtained by short time synthesis was active and selective in the hydrodenitrogenation (HDN)reaction of indole. Main advantage of the present study is the reduction of time and cost in the synthesis of the new material and the applicability for HDT reactions.
