A strong influence of the amount of the Co3O4 promoter on the catalytic performance in methanol oxidation of different gold catalysts supported on ceria was observed. The activity followed the order: Au/10 wt% Co3O4-doped CeO2 > Au/5 wt% Co3O4-doped CeO2 > Au/15 wt% Co3O4-doped...
FTIR studies on the selective oxidation and combustion of light hydrocarbons at metal oxide surfaces. Part 2.—Propane and propene oxidation on Co3O4 The interaction of propane and propene and of C3, C2 and C1 oxygenates (propane-1-ol, propan-2-ol, allyl alcohol, acetone, propanal, acrolein...
The values of the optical energy gap were reduced after the addition of Co3O4 nanoparticles. Meanwhile, the electrical conductivity of CMC/PAM-Co3O4 was increased with an increase of Co3O4 NPs at room temperature. The AC conductivity and the dielectric properties were carried out of the ...
NO was adsorbed in a mononitrosyl form as shown in the region of 1 937―1 939 cm~(-1) as a minor species. Samples [Co + Mg ( Sr)]/ZSM-5 showed a new band near 1 858 cm~(-1) (w) attributable to the species of Co_3O_4―NO. It was found that zeolite [Co + Mg (Sr)...
Adsorption of CO and the co-adsorption of CO/O2 over the cobalt oxides were further tested by in situ FTIR. It was shown that Co3O4 is quite active for the oxidation of CO at room temperature in the presence of oxygen, leading to the formation of CO2. The variation in the oxidation ...
Zinc cobalt doped Phosphate glasses with a chemical composition 45P2O5–4Co3O4–(11?+?x) Na2O–(40???x) ZnO where (x?=?0, 2, 4, 6, 8 and 10?mol%) were prepared by the conventional melt-quenching technique. These glasses were characterized using Fourier-Transform Infrared (FTIR). ...
