Probing surface hydroxyls of sub-micron FeOOH particles by Sum Frequency Generation Spectroscopy
EMSL Project ID
46395
Abstract
This work was devised to contribute to a new basis of understanding of mineral surface reactivity using Sum Frequency Generation (SFG) spectroscopy. As it is primordially focused on FeOOH minerals in contact with water it addresses key issues of atmospheric and geochemical importance. Our work will specifically be focused on reacting sub-micron particles with gaseous and liquid water. It will build upon Fourier transform infrared spectroscopy work carried out on the same particles at Umea University, and specifically focus on resolving involving reactive hydroxyl functional groups (e.g. protonation, hydrogen bonding and solvation). Concerted molecular dynamics simulations of the same surfaces will support interpretations of SFG spectra.
