Title of PhD project: Vibrational Spectroscopy of Quinoline and Quinoline Derivatives on Hydrated Pt (111) surface From First-Principle Approaches Introduction Cinchonidine (a cinchona alkaloid) is a chiral modifier providing enantioselectivity for a supported Pt catalyst in solvent conditions The investigation of a Pt(111) – cinchonidine system is challenging both theoretically and experimentally We study quinoline on a Pt (111) surface. Quinoline is the part of cinchonidine that directly Interacts with Pt. quinoline
Project outline A) UHV conditions -Investigation of adsorption and vibrations of quinoline & quinoline derivatives on Pt (111) surface using DFT (VASP code by G. Kresse, J. Furthmüller ) -IRAS simulations -STM and IETS simulations B) Hydrated surfaces: Studies of the effect of the solvent (water) on the adsorption and vibrational properties
Preliminary results:adsorption of quinoline on a Pt(111) surface Most stable adsorption geometry: BB- 10 7 ( 4,5,8,3 910 67 ) Eads= - 2,123066eV Top view Side view
