Název v původním jazyce
Electrochemical performance of cobalt hydroxide nanosheets formed by the delamination of layered cobalt hydroxide in water
Popis výsledku v původním jazyce
We report the preparation of monometallic Co2+/Co3+ layered double hydroxide, intercalated with lactate anions (LCoH-Lactate), and its spontaneous delamination in water to form cobalt hydroxide nanosheets. These hydroxide nanosheets formed stable aqueousdispersions. The thickness of a nanosheet was estimated to be approximately 1 nm by atomic force microscopy and small angle X-ray scattering experiments, and corresponds to a single hydroxide layer. Some of the Co2+ cations were oxidised by oxygen, resulting in a mixed Co0.762+Co0.243+ layer composition. Upon water evaporation, the nanosheets restacked to form transparent self-standing films with a layered structure like that of the original material. The coverage of the surface with side-by-side stacks of nanosheets indicated two-dimensional agglomeration and suggested that these dispersions could be applied to prepare large monolayers of nanosheets. The layers prepared by spin-coating were stable and featured reversible and reproduci
