Electrochemical performance of cobalt hydroxide nanosheets formed by the delamination of layered cobalt hydroxide in water.
We report the preparation of monometallic Co(2+)/Co(3+) 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 aqueous dispersions. The thickness of a nanosheet was estimated to be approximately 1 nm by atomic force microscopy and small angle X-ray scatteri...
متن کاملPamoate intercalated Zn-Al layered double hydroxide for the formation of layered organic-inorganic intercalate
A layered organic-inorganic intercalate was prepared by the self-assembly technique using pamoate (PA) as an organic guest in the Zn-Al layered double hydroxide inorganic host (ZAPAN). Various concentrations of PA, ranging from 0.01 to 0.04 M, were used to prepare the intercalated compound with a constant 4:1 ratio of Zn:Al in the mother liquor. The concentration of PA of 0.02 M at pH 7 was fou...
متن کاملHollow nanoshell of layered double hydroxide.
Hollow nanoshells of layered double hydroxide (LDH) have been fabricated using exfoliated LDH nanosheets as a shell building block and polystyrene beads as a sacrificial template.
متن کاملFormation of CoAl layered double hydroxide on the boehmite surface and its role in tungstate sorption.
Sorption of tungstate on boehmite (γ-AlOOH) is increased by co-sorption with Co2+ over the near-neutral pH range. Batch uptake experiments show up to a 3-fold increase in tungstate uptake over the range WO42-=50-1000μmol/L compared to boehmite not treated with Co2+. Desorption experiments reveal a corresponding decrease in sorption reversibility for tungstate co-sorbed with Co2+. Reaction of bo...
متن کاملThe formation of ordered heterostructures during the intercalation of phosphonic acids into a layered double hydroxide.
The intercalation reactions have been studied using in situ energy dispersive X-ray diffraction; ordered second stage heterostructures were observed as intermediate phases, which is almost unprecedented for rigid layer host materials.
