“…shows the IR spectra of the CeO2-HSA (black line) and the isotopically exchanged 18-O CeO2-HSA (blue line) samples after co-adsorption of cyclohexane and tBut-OOH together with the corresponding gas phase spectra. Both Cy-18 O (solid lines) and Cy-16 O (dashed lines) alkoxy species were observed on the 18-O CeO2-HSA (blue line) sample, confirming the Mars van Krevelen mechanism where oxygen lattice species are involved in the oxidation process and further replenished by 16-O species coming from tBut-16 O16 OH. The identification of gas phase Cy18 OH is challenging due to the overlapping by gas phase Cy16 OH, which shows a broad and asymmetric IR band.…”

“…An additional point in the deperoxidation process is the possibility to use the oxygen in the hydroperoxide to simultaneously oxidize the alkane solvent, thus obtaining selectivities to K/A-oil larger than 100%. Such selectivities have been reported for homogeneous catalysts containing Ru [15,16] and Os [17] in liquid phase, but not for heterogeneous solid systems.…”

“…Rutenioporfirinas têm sido estudadas como catalisadores em diversos tipos de reações como, por exemplo, hidroxilação de cicloexano 1 , ciclopropanações 2,3 , reações de epoxidação 4 , detecção de oxigênio 5 , modelos para eficiência catalítica do citocromo P450 6 etc. Tal diversidade de reações catalisadas pode ser explicada, em parte, pela grande afinidade do complexo metaloporfirínico com átomos de oxigênio 7 provindos, em muitos casos, de moléculas doadoras de oxigênio como, por exemplo, o iodosilbenzeno 8,9 , peróxido de hidrogênio 10 , monoperoxoftalatos 11 , hipoclorito de sódio 12 etc.…”
