The results showed an increasing in refractive index, permittivity, extinction coefficient, dielectric constants, electric susceptibility and polarizability with increasing Co 3 O 4 content. Cobalt ions produced intense blue color in glass and used as optical filters in UV–VIS region. Fourier-transform...
谢谢您的回复，回头再多做几个FTIR看看，可能Co2+和Co3+的问题可以通过XPS来验证。因为这两个样品的...
不过恕我直言，仅凭这两张图，很难极具说服力的表达些事情。相对强度变化不明显，可能是仪器试验误差。
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...

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, acrylic, pro... E Finocchio,G Busca,V Lorenzelli,... - 《Journal of the Chemical Society》...
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 ...
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 ...
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)]/ZSM-5 exhibits superior performance characteristics for SCR of NO molecules, and is promising as a useful catalyst....
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). ...
