Construction of high-proportion ternary dual Z-scheme Co3O4/NiCo2O4/NiO photocatalytic system via incomplete solid phase chemical reactions of Co(OH)2 and Ni(OH)2 for organic pollutant degradation with simultaneous hydrogen production

Tuning the annealing temperature to achieve heterostructured nanofibers for high performance lithium-ion batteries

“…The presence of Ni 3+ can only be related to the formation of NiCo 2 O 4 , which strongly proves the incomplete chemical reaction between NiCo 2 O 4 , Co 3 O 4 and NiO. 55,57,58 As the annealing temperature increases, the proportion of Co 2+ peak area decreases (Fig. 2b and c), i.e.…”

“…Because the diffraction peaks of Co 3 O 4 overlap with those of NiCo 2 O 4 , it is necessary to use the zoomed-in view to distinguish between them. 39,55,56 44.61 (Fig. 1d).…”

“…Because the diffraction peaks of Co 3 O 4 overlap with those of NiCo 2 O 4 , it is necessary to use the zoomed-in view to distinguish between them. 39,55,56 Fig. 1c shows a zoomed-in view near 36.7°, where the peak is a superposition of the NiCo 2 O 4 and Co 3 O 4 diffraction peaks.…”

Efficient Removal of Inorganic and Organic Pollutants over a NiCo2O4@MOF-801@MIL88A Photocatalyst: The Significance of Ternary Heterojunction Engineering

“…Its main feature is the change of morphology along with the change of conditions and synthesis methods. 33 , 34 For cobaltite synthesis, many methods, such as hydrothermal/solvothermal, electrodeposition, electrospinning, template method, etc., have been reported. By changing the reaction conditions like solution pH, temperature, reaction time, type and amount of solvent, and the ratio of precursors, different morphologies and surfaces can be obtained.…”

“…Nickel cobaltite is widely used due to its magnetic properties, narrow bandgap, and inexpensive precursors. Its main feature is the change of morphology along with the change of conditions and synthesis methods. , For cobaltite synthesis, many methods, such as hydrothermal/solvothermal, electrodeposition, electrospinning, template method, etc., have been reported. By changing the reaction conditions like solution pH, temperature, reaction time, type and amount of solvent, and the ratio of precursors, different morphologies and surfaces can be obtained. , Among all the available methods, hydro/solvothermal methods have advantages such as simplicity, uniformity, less polluting products, controllability, and low energy utilization .…”
