Radiation IR spectra

The samples were characterized by means of X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), electron diffraction (ED), and Mossbauer spectroscopy. XRD analysis was carried out on a HZG-4A diffractometer by using Ni-filtered Co Ka radiation. IR-spectra were recorded on an AVATAR FTIR-330 spectrometer. TEM/ED examinations were performed with a LEO 906E and a JEOL 4000 EX transmission electron microscopes. The resonance spectra were recorded in air at 298 K and processed by using a commercial SM2201 MSssbauer spectrometer equipped with a 15 mCi Co (Rh) source. 

XRD measurement was carried out using TUR 62-M diffractometer with CuKa radiation. IR spectra (KBr) were recorded on Perkin-Elmer 580. The diffuse reflectance spectra were measured using self-supported wafers. The samples were evacuated at 500°C for 4 hours prior to measurement. The Perkin-Elmer 580 B and Beckman-Acta M VII Spectrometers were equipped with DR units. The details of procedure were described elsewhere [6]. Probe molecules (CO, ethylene, d4-ethylene, d3-acetonitrile) were adsorbed on the samples SnAlPO-0.1 at room temperature and their spectra were recorded. 

The catalysts were prepared by impregnating Ca(OH)2 with aqueous solution of NaOH applying the incipient wetness method. After impregnation the samples were dried and calcined in CO2 free air at 973 K. Other alkaline earth oxides (Analar) were also used for activity measurements. X-ray diffraction studies were carried out in a Phillips instrument using a Guinier camera applying crystal reflected monochromatic CuK a radiation. IR spectra were recorded by a Perkin-Elmer FTIR 1710 spectrometer. The samples were dried for 1 Oh at 383 K prior to preparing the pellets. The catalytic experiments were carried out in a quartz made reactor, details of the reactor operation and product analysis have been described elswhere [8]. 

The synthesized samples of electrolytes, cathode and anode materials were characterized by powder X-ray diffraction (XRD) and infrared (IR) spectroscopy. The XRD spectra were obtained with URD-6M or Dron-3M diffractometers using Cu K radiation. IR spectra from 4000 to 400 cm were recorded with a Shimadzu FTlR-8300 spectrometer using KBr pellets.
