Abstract Details

2014, Doctor of Philosophy, Case Western Reserve University, Chemistry.
A multilayer system denoted as Pt/TiN/Ti/Si(111) was created in UHV. Chemical and physical properties of these layers were studied with XPS and ARXPS. Results of the analysis shows that a ca. 1nm thick titanium nitride layer between platinum and silicon was sufficient to stop diffusion of Pt to Si at room temperature. Nature of the interaction of thin layers of Pt on titanium nitride showed that initially deposited monolayer of Pt produced Pt/Ti intermetallic compound while properties of subsequent layers suggested metallic Pt. Relevance and conclusions were discussed in relation to titanium nitride as a catalyst support in PEM fuel cells. Hydroxylamine was successfully deposited in UHV on well characterized clean and oxygen covered Pt(100). RAIRS analysis suggests specific orientation of hydroxylamine molecule on clean Pt(100) and non-specific adsorption in case of oxygen covered Pt(100). Subsequent heating was followed by desorption in case of clean Pt(100) and by chemical reaction in case of oxygen covered Pt(100).Relevance and conclusions were discussed in relation to nitrogen cycle and electrocatalytic denitrification.
