Selective oxidation of cyclohexene over RuO2/Co3O4 nanocatalystunder mild conditions

In this study, RuO2 nanoparticles on Co3O4 were prepared by wetness impregnation method, which wasprecipitated by alkali-hydrolysis of RuCl3 on the surface of Co3O4 and transformed into RuO2/Co3O4catalyst by calcinations. The catalysts were investigated with XRD, XPS, TEM, and BET techniques andwere tested for oxidation of cyclohexene. The nano-catalyst demonstrated high catalytic activities for theoxidation of cyclohexene to the 2-cyclohexen-1-one under heterogeneous condition. In order to obtainmaximum conversion of cyclohexene, the reaction parameters, like reaction temperature and time, wereoptimized. Under the optimized conditions, a maximum of 95% cyclohexene conversion and 97%selectivity, was achieved with RuO2/Co3O4 mixed oxide nano-catalyst.
