dc.description.abstract |
Various characterization techniques, including UV-Vis, FTIR, EPR and XPS, were used for the description of structural changes in Fe-silicalite with low concentration of iron, which was activated using different methods (by conventional hydrothermal pretreatment at 600 °C and by treatment in the diluted flow of ammonia and propane in helium at 540 °C). Activated Fe-silicalite was subsequently used as a catalyst for the direct ammoxidation of propane. It has been shown that the studied methods of activation lead to materials with different catalytic behavior (activation in the flow of ammonia and propane resulting in the more active and selective catalytic materials). Results from the catalytic test are further discussed together with the results from the characterization of activated samples. |

This work deals with the use of laser-induced breakdown spectroscopy (LIBS) for determining the surface density of titanium in ultrathin layers, particularly in ultrathin layers on a steel sheet. The results obtained by LIBS spectroscopy were compared with those obtained by wavelength dispersive X-ray fluorescence spectroscopy (WDXRF), X-ray photoelectron spectroscopy (XPS) and laser ablation inductively coupled plasma time of flight mass spectrometry (LA-ICP-TOF-MS). A simple, cheap and efficient method for the determination of the surface density of titanium in thin layers has been developed. |
