3D Hierarchically Assembled Porous Wrinkled-Paper-like Structure of ZnCo2O4 and Co-ZnO@C as Anode Materials for Lithium-Ion Batteries

“…Among the various transition metal oxides explored, Co 3 O 4 is one of the most promising candidates as anode material for LIBs for its high theoretical capacity (890 mAhg –1 ) and excellent cycle life. − ,,,− However, because of the high cost and toxic nature of cobalt intensive efforts have been made to replace cobalt partially from Co 3 O 4 by a cost-effective and eco-friendly metal without loss of its electrochemical properties. In this respect, cobalt based ternary metal oxide, ZnCo 2 O 4 is very attractive as zinc is cheap, abundant and electrochemically active toward lithium. − Similar to Co 3 O 4 , it is a normal spinel, where the Zn 2+ occupying the tetrahedral sites and Co 3+ occupying the octahedral sites. As the morphology and microstructures of nanostructure materials are crucial for their electrochemical performance, ZnCo 2 O 4 with varying morphology, which includes 1D wire and their 3D assembly, tubes and 2D disk have been developed and their performances as anode material in LIBs have been evaluated. − Qiu et al, Hu et al, and Li et al reported the ethylene glycol directed glycolate intermediate based hydrothermal/solvothermal synthesis of ZnCo 2 O 4 random flake, microsphere, and yolk-shelled ZnCo 2 O 4 microspheres, respectively.…”

Elastic, phonon and thermodynamic properties of ZnAl2O4 and ZnAl2S4 compounds from first–principles calculations

“…At present, first-principles techniques have been demonstrated to be able to accurately describe the electronic structures, mechanical properties, optical and phonon spectra for different materials including ZAO [5][6][7][8][9]. Khenata et al [10] studied the structural, electronic and elastic properties of ZAO using the full potential linear augmented plane wave (FP-LAPW) method as implemented in the WIEN97 code.…”

Transport and magnetic properties of ZnCo2O4/Si heterostructures grown by radio frequency magnetron sputtering

“…Element doped ZnO/Si heterostructures are expected to be a potential way to improve the photovoltaic efficiency. ZnCo 2 O 4 thin film is recently confirmed to be one of good candidates [13]. Nevertheless, their transport behaviors have not been reported yet.…”

“…ZnCo 2 O 4 , which is a spinel oxide with strong ferromagnetism and high Curie temperatures (Tc) greatly exceeding room temperature [13,[18][19][20] constitutes another class of ferromagnetic semiconductors. Although there are numbers of studies on cobalt doped ZnO [21][22][23][24][25][26], the ferromagnetism of n-type and p-type ZnCo 2 O 4 is a continuous debate and the microscopic origins of this ferromagnetism remain poorly understood.…”
