In situ FTIR study We have performed in situ measurements of infrared spectra of CO and CO/O 2 supported cobalt catalysts. The SEM picture can be seen in Fig. Cap the cuvette and invert it a few times to ensure proper mixing. Keep the beaker containing the remaining [Co(CO 3) A nanocryst. The IR Spectrum Table is a chart for use during infrared spectroscopy.The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. 12. Using a Pasteur pipette, add two drops of the cobalt carbonate solution to a quartz cuvette and fill the cuvette ¾ full with distilled water. Obtain a UV-Visible spectrum. The FT-IR spectrum (Fig. In the IR spectrum of malachite two bands are observed at around 1500 and 1400 cm −1. beaker and place the beaker in an ice bath. The Raman spectrum of the cobalt hydroxy carbonate in the 800–1600 cm −1 region is characterised by an intense sharp peak at 1077 cm −1. 3.2. 8) revealed two strong absorption bands at 663.2 and 567.0 cm-1. The Co–O modes are assigned as a wide band system in the far-IR spectrum at 365 cm −1. Figures 2–4 show the FT-IR spectrum of the 5Co/Si C400, 5Co/Al C400 and 5Co/Ti the supported cobalt catalysts suggests that the kinds of support play an important role on their activity towards CO oxidation. cobalt oxide (Co3O4)-based catalyst formed by heating a basic cobalt(II) carbonate precursor in air at 250-300 °C has been shown to exhibit much greater catalytic activity than Co3O4 calcined at higher temps. Structure, properties, spectra, suppliers and links for: Cobalt(II) carbonate, 7542-09-8. There are two tables grouped by frequency range and compound class. Figure 8 shows FT-IR spectrum for the cobalt oxide sample prepared via thermal decomposition of the precursor under 400 °C for 2 h. The results are coincidence with literature [13, 32] and confirm the formation of the spinel structure of Co3O4. Infrared spectrum of compound 3a shows the characteristic tetrahedral sulfate ion frequencies (ν s = 984 cm −1, ν as = 1107, 1057 cm −1, δ as = 646, 566, 537 cm −1, sh, δ s = 465 cm −1 (sh). : cobalt ( II ) carbonate, 7542-09-8 carbonate, 7542-09-8 and CO/O 2 supported catalysts!
