Formation of cobalt hydroxide single-crystal platelets from pulsed laser deposited cobalt thin film

From scrap metal to highly efficient electrodes: harnessing the nanotextured surface of swarf for effective utilisation of Pt and Co for hydrogen production

“…3d), which is attributed to Co(OH) 2 consistent with Co oxidation aer atomic deposition. 27,28 Doubling the Co amount in Co30-Ni increased the coverage of the swarf surface with Co(OH) 2 forming a network of interlinking akes ∼100 nm in diameter (Fig. 3e).…”

Effect of synthesis parameters on cobalt oxide nanostructures morphology

“…Numerous research endeavors have been dedicated to the development of synthetic methodologies for the growth of cobalt oxide nanostructures, encompassing hydrothermal [19], electrospinning [20], chemical vapor deposition [1], sputtering [21] and pulsed laser deposition [22], among others. However, most of these deposition techniques entail demanding parameters such as high temperature, high vacuum, and complex reaction conditions, which ultimately lead to high production costs and impede widespread utilization of these materials.…”

One-step fabrication of 3D hierarchical Ni-incorporated β-Co(OH)2 assembled by 2D center disk and 1D length-tunable brush

“…As one of the most versatile transition hydroxides, cobalt and nickel hydroxide and their derived oxides have been widely used in alkaline rechargeable batteries, gas sensors, supercapacitors, heterogeneous catalysis, fuel cell electrodes and magnetic materials. [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] Various nanostructures of cobalt or nickel hydroxide and oxide such as platelets, [22][23][24][25] rods, 26 tubes, 27 wires, 28,29 cubes, [30][31][32] butterfly-like structure, 33 urchin-like structure 34,35 and hollow spheres 36,37 have been fabricated via different chemical routes. Apart from the product morphology, spatial size and surface structure of materials, chemical composition is also of fundamental importance in determining the outcome of the properties.…”
