In this work, we study cyclohexene oxidation by molecular oxygen on doped‐ TiO 2 . The improvement of the oxidizing capacity of titanium oxide by doping with iron oxide at different molar ratios is checked. All materials with different molar ratios (Ti/Fe = 9, 4, and 2) are prepared by the sol–gel method and fully characterized by ICP , XRD , SEM , DR / UV –vis, IR , and N 2 adsorption/desorption. The results show that iron is successfully incorporated into the titanium matrix but the incorporated amount is limited. In catalytic tests, improved activity is noticed while using TiO 2 in the presence of Fe 2 O 3 , which is due the improved oxidation. Conversion in the range of 21–42% depending on the presence of iron oxide was obtained with excellent yield of adipic acid (97% selectivity).
