Their catalytic behavior was studied in cylohexanol conversion. Materials with high surface area and well-ordered pore structure were obtained. All modified mesoporous silicas possess high activity in cyclohexanol conversion. Bicomponent FeTiMCM-41 catalyst pretreated in hydrogen at 723K presented the highest activity and selectivity to cyclohexanone.
