Fecha de publicación: | sep-2002 | Editor: | Elsevier | Citación: | Electrochemistry Communications 4(9): 684-689 (2002) | Resumen: | Electrochemical oxidation at room temperature of a slurry of Ag2Cu2O3 yields a new silver copper oxide, formulated as Ag2Cu2O4, with one more atom of oxygen per unit formula, that can in turn revert to the original precursor. The resulting oxide presents a different electronic and crystal structure from its precursor, as shown by XPS, X-ray and electron diffraction. This phase transformation involves a radical structural change from a 3D to a 2D network, as well as electronic changes involving silver and oxygen. The potential of electrochemical techniques to induce crystal-chemical solid state transformations is analyzed. | Versión del editor: | http://dx.doi.org/10.1016/S1388-2481(02)00433-2 | URI: | http://hdl.handle.net/10261/15854 | DOI: | 10.1016/S1388-2481(02)00433-2 | ISSN: | 1388-2481 |
