Abstract
The surface of SiO2 in contact with a liquid has been studied in situ by Fourier transform infrared spectroscopy, electrochemistry and ab initio quantum chemical calculations. Experimental issues arising from the cell designed have been addressed, notably the influence of the medium above the SiO2 film on the line shape of the Si–O vibrations. Using electrical potential control of the surface with electrochemistry, the hydrated states of the SiO2 surface have been identified, featuring a neutral SiOH species and pentavalent Si(OH)OH− anionic centers.
