Direct growth of urchin-like CuCo2O4 on Ni foam for ultrahigh capacity and excellent rate ability of lithium ion batteries

Solvothermal Synthesis of Mesoporous 3D‐CuCo2O4 Hollow Tubes as Efficient Electrocatalysts for Methanol Electro‐Oxidation

“…As for the O1s spectra, three kinds of oxygen species are observed as shown in Figure d. The high intensity peak at O 1 (529.65 eV) is attributed to the metal (Cu/Co) oxygen bond, while the fitting peaks at O 2 (531 eV) and O 3 (532.2 eV) correspond to the oxygen defects of small‐particle metal oxide and physically chemisorbed water molecules, respectively …”

“…Transition metal oxides improve electrocatalytic performances thanks to their enhanced surface area and short electron‐ion‐transport pathways . In particular, CuCo 2 O 4 has been widely used as promising electrocatalysts for Li‐ion batteries and supercapacitors due to their abundance, high theoretical capacity, low cost, ease of preparation, and environmental friendliness . More significantly, CuCo 2 O 4 has a higher electrochemical performance than the single component metal oxides, copper oxides and cobalt oxides, since addition of metal ion affects the morphology, particle size, and surface area of the electrocatalyst …”

Enhancement of photoelectrocatalytic performance of copper cobaltate nanoflowers modified with 5,10,15,20-tetrakis(4-carboxylphenyl)porphyrin for methanol oxidation under light

“…10,11 Among them, CuCo 2 O 4 has been used in supercapacitors and Li-ion batteries because of its advantages such as environmental protection, low cost, and easy preparation. [12][13][14] Moreover, Jadhav et al have reported the three-dimensional flower-like CuCo 2 O 4 grown on nickel foam substrate, which exhibits excellent methanol electrooxidation performance. 15 Subsequently, Kumar et al 16 have introduced the cationic vacancy in CuCo 2 O 4 by doping boron, which shows higher MOR performance than that of CuCo 2 O 4 .…”
