Effects of dodecyl sulfate and nitrate anions on the supercapacitive properties of α-Co(OH) 2

Layered Double Hydroxide Hollowcages with Adjustable Layer Spacing for High Performance Hybrid Supercapacitor

“…As shown in Figure 3b, each sample has an intense and broad peak at 3456 cm −1 , which is attributed to the O-H stretching vibration, implying the existence of certain water molecules in each sample. [26] Except for the CoNi-LDH sample, there are symmetric and asymmetric modes of the coordinated -COO group and aromatic skeletal C-H at 1386, 1571, and 752 cm −1 . When the H 2 BDC ligand is intercalated into the layer of CoNi-LDH, parts of H 2 BDC will coordinate with cobalt and nickel ions.…”

A porous Co(OH)2 material derived from a MOF template and its superior energy storage performance for supercapacitors

“…Therefore, Co(OH) 2 is a promising candidate as a supercapacitor electrode material due to its high theoretical specic capacitance (3458 F g À1 ), layered structure, low cost and environmental friendly physicochemical features. 7,8 Metal-organic frameworks (MOFs) are novel porous materials with structures that are controllable by changing the metal ions, organic bridging ligands and reaction conditions. 9 MOFs with high specic surface area, adjustable pore size and different topological structures are destined to be promising materials for gas storage, 10 sensors, 11 catalysis, 12 separation 13,14 and energy storage.…”

Structural engineering and electronic state tuning optimization of molybdenum-doped cobalt hydroxide nanosheet self-assembled hierarchical microtubules for efficient electrocatalytic oxygen evolution

“…This indicates that Mo doping leads to the structural change in the cobalt hydroxide. Two possibilities of Mo doping in cobalt hydroxide nanosheets have been speculated according to literature [38]. As shown in Fig.…”
