Cyclohexane heterogeneous catalysis

Heterogeneous Catalysis for Cyclohexane Oxidation to Either Ol/One or AA (Various Oxidants Included)... 

The length scale plays a vital role in heterogeneous catalysis to control the structure, active phase and overall framework of the catalyst system. In the CMR, catalysis by nano-scale materials will improve the physico-chemical properties of the catalytic membrane. A uniform nanostructured catalytic membrane was prepared using AAO and atomic layer deposition techniques and tested in oxidative dehydrogenation of cyclohexane. Nanostructured CMs have excellent properties, such as uniform pores, contact time control, uniform diffusion paths and active site isolation (no sintering), compared... 

Recently, Corma et al. have patented a process of oxidizing cycloalkane with molecular oxygen to produce cycloalkanol and/or cycloalkanone in the presence of hydrotalcite-intercalated heteropoly anion [Co MnCo (H20)039] (M = W or Mo), which comprised one cobalt as a central atom and another as a substitute of a W=0 fragment in the Keggin structure [98]. At 130 °C and 0.5 MPa, 64 and 24% selectivity to cyclohexanone and cyclohexanol, respectively, was achieved at cyclohexane conversion about 5%. This catalytic system could be of practical importance provided a true heterogeneous nature of catalysis and good catalyst recyclability had been proved. Unfortunately, this information was lacking in [98].
