Vibrational Spectroscopy of Water at Liquid/Solid Interfaces: Crossing the Isoelectric Point of a Solid Surface

Adsorption and surface oxidation of Fe(II) on metal (hydr)oxides

“…As discussed in Hiemstra and van Riemsdijk (2006), the double layer structure that emerges can be explained by the alignment of water molecules near the surface in several layers, in which the electrolyte ions can only change stepwise their position. This picture agrees with experimental information obtained by different valuable approaches like force measurements (Pashley and Israelachvili, 1984;Israelachvili and Wennerstrom, 1996), X-ray reflectivity (Toney et al, 1995;Fenter and Sturchio, 2004;Catalano et al, 2006) and Sum Frequency Spectroscopy (Yeganeh et al, 1999;Kataoka et al, 2004;Ostroverkhov et al, 2005;Shen and Ostroverkhov, 2006). These measurements show increase in the ordering of water within a distance of about 0.7-0.9 nm, which is equivalent to about 2-3 layers of water molecules .…”

“…These measurements show increase in the ordering of water within a distance of about 0.7-0.9 nm, which is equivalent to about 2-3 layers of water molecules . Sum Frequency Spectroscopy for silica, quartz, Al 2 O 3 (s), and TiO 2 (s) (Shen and Ostroverkhov, 2006) shows that the number and orientation of polar water molecules changes with the interface charge (Yeganeh et al, 1999;Ostroverkhov et al, 2005). In case of the introduction of charge at the surface due to ion adsorption, water dipoles will orient in the electrostatic field.…”

Potential-dependent structure of the interfacial water on the gold electrode

“…Thus, the upward SFG peak should become a downward dip if the interfacial water molecules flip when the potential was changed from negative to positive across the pzc because the flipping of interfacial water molecules gives the inverse phase relative to the nonresonant contribution from the gold [24,26,30,31]. It is clearly demonstrated in Fig.…”

Effect of pH on the Water/α-Al2O3 (11̅02) Interface Structure Studied by Sum-Frequency Vibrational Spectroscopy

“…Yeganeh et al first used SFVS to probe the corundum/water interfacial structure at different pH values, but the crystalline surface they employed was not specified. 14 There have been several recent reports of studies on water/-Al 2 O 3 (0001) interfaces by SFVS. [15][16][17] However, to our knowledge, water/-Al 2 O 3 interfaces cut in different well-defined orientations/have not yet been explored by SFVS.…”
