Temperature-dependent crystallization of Cu₂O rhombic dodecahedra

Abstract

Size and shape uniformity of nanomaterials are extremely important for their applications in batteries, supercapacitors, catalysis, etc. In the crystallization process, finding proper synthesis condition is necessary to control over...

Hierarchical Nanocages Assembled by NiCo-Layered Double Hydroxide Nanosheets for a High-Performance Hybrid Supercapacitor

“…As can been seen from the figure, the values of b for cathodic and anodic peaks corresponding to NiCo-LDH-210 are 0.64 and 0.68, respectively, indicating that the charge storage is dominated by a combination of capacitive and diffusion-control mechanisms. Then, the capacitive (k 1 ν) and diffusion-controlled (k 2 ν 1/2 ) contributions to the total capacitance can be quantitatively calculated based on the equation: i ( V ) = k 1 ν + k 2 ν 1/2 , , where k 1 and k 2 are parameters, and i is the response current at a fixed potential ( V ). The CV decoupling result of NiCo-LDH-210 at 20 mV s –1 depicted a diffusion-controlled contribution of 22.31% from the total capacitance (Figure f).…”

Seeded growth of gold-based nanostructures regulated by controlled doping

“…Generally, polyhedra with different ratios of exposed {100}, {111}, and {110} crystal planes have been grown by adjusting reaction and crystallization kinetics that might deserve research attention in the future. 65,66 In particular, if the doping element can adsorb on the metal particle surface via covalent bonding, it can also coordinate with the metal complex (i.e. metal precursor) via similar bonding.…”

Facet-controlled synthesis and morphological evolution of Cu2O microcrystals

“…[9][10][11][12][13][14][15][16] Because Cu 2 O exhibits various morphologies as a result of its cubic crystal system, Cu 2 O is the most studied inorganic compound for facet-and morphology-controlled synthesis. [17][18][19][20][21] Simple shapes with low-index facets are cubes, octahedra, and the rhombic dodecahedra. Cubic, octahedral, and rhombic dodecahedral Cu 2 O crystals have six {100} facets, eight {111} facets, and twelve {110} facets.…”
