Using diffuse reflectance FTIR spectroscopy, the stretching vibrations of the terminal Mo= O (995 cm 1) and the bridging Mo-O-Mo (820 cm 1) bands were monitored while MoO 3 powders are heated from 25 to 350掳C at a hydrogen pressure of 6 atm. It was found that some discernible ...
while in the samples with higher diamine the amine is monoprotonated due to the higher basicity of these samples. The samples with higher diamine also contained ammonium cations (NH4+) in order to achieve electroneutrality [28]. The release of ammonia observed in the TG-FTIR measurements underli...

The recorded FTIR spectra (see Fig. s4) for undoped sample and samples doped with 10%, 25%, 50%, and 75% Eu3+ showed no significant differences between each other. Spectra consisted of several overlapping strong absorption bands in the range of 500–1000 cm−1. These bands can be ...
Characterization results (BET, XRD, XPS, FTIR, and TPR) showed that their structure and properties depend on the composition of the calcined samples and the calcined conditions. Catalytic tests showed that relatively high isobutane conversion and desired product selectivity can be achieved over MoV0.3...
The in situ DRIFTS spectra of the CeO2 sample were collected by using a Bruker Vertex 70 FTIR spectrometer. An acquisition time of 30 s at a resolution of 4 cm−1 was used for the spectrum collection. The DRIFTS cell (Harrick) was equipped with CaF2 windows and a heating cartridge...
