Hydrothermally synthesized microrods and microballs of NiCo2O4 for supercapacitor application

Elevating Supercapacitor Performance of Co3O4-g-C3N4 Nanocomposites Fabricated via the Hydrothermal Method

“…The oxygen deconvolution spectra are displayed in Figure 2 c, with three peaks at 529.07 eV, 530.24 eV, and 531.21 eV. The presence of metal oxide (Co-O) is demonstrated by the peak at 529.07 eV, whereas the presence of oxygen ions in nanoparticles and adsorbed water is shown by the peaks at 530.24 eV and 531.21 eV, respectively [ 26 , 27 , 28 ]. Figure 2 d additionally displays the carbon deconvolution spectra, which have three separate peak locations at 287.53 eV, 285.51 eV, and 284.10 eV, representing carbon bonds in C=O, C-N, and C-C, respectively [ 29 , 30 , 31 ].…”

Temperature dependent fabrication of various rod and rhombohedral-shaped mesoporous Co3O4 crystals and their capability towards elimination of toxic Cr(vi) ions from the aquatic environment

“…There are also a few research studies based on heavy metal removal by using different metal oxides and ferrite like materials. [26][27][28][29][30][31] Annually chemical waste coming out from diverse factories and industries leads to remarkable eco-system and environmental pollution. Most of the colored effluents including toxic metal compounds are discharged into various water bodies, for example, seawater, ponds, rivers, etc.…”

Oxygen defect-mediated NiCo2O4 nanosheets as the electrode for pseudocapacitors with improved rate capability

“…Among them, spinel NiCo 2 O 4 has drawn particular attention due to its low cost, high availability, complex chemical composition and multiple cation valence. [21][22][23][24][25][26][27] For example, Yan et al have prepared an integrated electrode with abundant channels wrapped by ultrathin NiCo 2 O 4 nanosheets. The resultant electrode delivers a high specific capacitance of 1541 F g À1 at a current density of 1 A g À1 , whereas the capacitance can be maintained at 72.7% with the current density up to 20 A g À1 .…”
