Catalyst Characterization II

This lecture delves into the advanced techniques used for catalyst characterization, focusing on the shifts in CO stretching frequency on Pt surfaces covered with hydrogen or oxygen. It covers the use of probe molecules like carbon monoxide, the Blyholder model, and the electronic state investigation of catalytic active sites. The lecture also explores reflection techniques, including DRIFTS and ATR-IRS, to study events at interfaces. Additionally, it discusses attenuated total reflection and its application in investigating solid-liquid interfaces. The lecture further examines UV-vis spectroscopy, electronic transitions, inorganic compounds, and the principles of ligand field theory in catalysis.
