Abstract

Zinc adsorption and interfacial hydration on yttria-stabilized zirconia (YSZ) surfaces in contact with aqueous zinc solutions at room temperature and neutral pH have been probed, with combined specular high-resolution X-ray reflectivity and element-specific (Zn) resonant anomalous X-ray reflectivity techniques. The total and partial zinc-Specific electron density profiles in the surface normal direction show the detailed interfacial hydration structures with zinc adsorption: Strongly depending on its crystallographic orientations, the YSZ (110) surface adsorbs zinc species only within adsorbed water layers above the terminal plane, while on (111) surface, zinc further-penetrates the substrate (below the terminal plane). Considering that both surfaces are enriched with oxygen vacancies and metal-depleted sites; on which chemisorbed water species are expected, the observed contrast indicates that specific zinc adsorption is controlled strongly by the intrinsic surface chemistry that results from orientation-dependent interfacial structures.

Orientation-dependent hydration structures at yttria-stabilized cubic zirconia surfaces

Journal Article Hou, Binyang ; Kim, Seunghyun ; Kim, Taeho ; ... - Journal of Physical Chemistry. C

Water interaction with surfaces is very important and plays key roles in many natural and technological processes. Because the experimental challenges that arise when studying the interaction water with specific crystalline surfaces, most studies on metal oxides have focused on powder samples, which averaged the interaction over different crystalline surfaces. As a result, studies on the crystal orientation-dependent interaction of water with metal oxides are rarely available in the literature. In this work, water adsorption at 8 mol % yttria-stabilized cubic single crystal zirconia (100) and (111) surfaces was studied in terms of interfacial hydration structures using high resolution X-raymore »« less

The hydration structure at yttria-stabilized cubic zirconia (110)-water interface with sub-Ångström resolution

Journal Article Hou, Binyang ; Kim, Seunghyun ; Kim, Taeho ; ... - Scientific Reports

The interfacial hydration structure of yttria-stabilized cubic zirconia (110) surface in contact with water was determined with ~0.5 Å resolution by high-resolution X-ray reflectivity measurement. The terminal layer shows a reduced electron density compared to the following substrate lattice layers, which indicates there are additional defects generated by metal depletion as well as intrinsic oxygen vacancies, both of which are apparently filled by water species. Above this top surface layer, two additional adsorbed layers are observed forming a characteristic interfacial hydration structure. The first adsorbed layer shows abnormally high density as pure water and likely includes metal species, whereas themore »« less

TEM observation of reaction at the interface between yttria-doped ceria and yttria-stabilized zirconia

Journal Article Mitsuyasu, Hidemi ; Nonaka, Yasushi ; Arai, Hiromichi - Journal of Solid State Chemistry

Interfacial reaction between yttria-stabilized zirconia (YSZ) and yttria-doped ceria (YDC) phases was analyzed by X-ray diffraction and high-resolution transmission electron microscopy. An X-ray diffraction pattern indicated that the mixture of YSZ and YDC consisted of their original phases after heating at 1100{degrees}C, whereas a solid state reaction occurred between them at higher temperatures. The solid state reaction proceeded as the Ce component was dissolved into the cubic YSZ phase, with an expense in the amount of the cubic YDC phase. The completion of the reaction gave a single cubic fluorite phase of Y-doped zirconia-ceria (YCZ) solid solution at 1500{degrees}C ormore »« less

Termination and hydration of forsteritic olivine (010) surface

Journal Article Yan, Hongping ; Park, Changyong ; Ahn, Gun ; ... - Geochimica et Cosmochimica Acta

Termination and hydration of the forsteritic (Fo90Fa10) olivine (010) surface have been investigated with high-resolution specular X-ray reflectivity and Atomic Force Microscopy. The surface was prepared by polishing a naturally grown {010} face, from which we found the polished surface in acidic (pH 3.5) alumina suspension exhibits regular steps while the basic (pH 9.5) silica polished surface is irregularly roughened, indicating there are two distinguishable mechanochemical processes for the surface dissolution. The quantitative interpretation of the regular steps from the alumina polished surface suggests that the observed step heights correspond to multiples of crystallographic unit cell. The terrace surface ismore »« less

Synthesis of Nanosize Yttria-Stabilized Zirconia by a Molecular Decomposition Process

Journal Article Yi, Jiang ; Bhide, Sanjeevani V ; Virkar, Anil V - Journal of Solid State Chemistry

Nanosize yttria-stabilized zirconia (YSZ) was synthesized by a novel approach based on molecular decomposition. In this approach, yttria-doped BaZrO{sub 3} (Y-BaZrO{sub 3}) or yttria-doped Na{sub 2}ZrO{sub 3} (Y-Na{sub 2}ZrO{sub 3}) precursors were first synthesized from BaCO{sub 3}, ZrO{sub 2}, and Y2O{sub 3} or BaCO{sub 3} and commercial YSZ for Y-BaZrO{sub 3}, and from Na2CO{sub 3} and YSZ for Y-Na2ZrO{sub 3}, by a conventional solid-state reaction method. The precursors were then boiled to leach away the unwanted species, BaO or Na{sub 2}O, either in a dilute HNO{sub 3} solution in water in the case of Y-BaZrO{sub 3}, or in deionized watermore »« less
