Coupling of nano-spinel MgFe2O4 on Co3O4 for heterogeneous photocatalysis and antibacterial applications: Insights of optoelectrical properties

Construction of Hollow Co3O4@ZnIn2S4 p-n Heterojunctions for Highly Efficient Photocatalytic Hydrogen Production

“…As shown in Figure 5 b, the Co 2p spectrum is composed of two spin-orbit doublets and two satellite peaks. The binding energies of the first peak in the composite Co 3 O 4 (20)@ZIS are at 779.70 eV and 781.36 eV, and the second peaks are at 794.28 eV and 796.03 eV, corresponding to the Co 2p 3/2 and Co 2p 1/2 orbitals, respectively, which indicate the coexistence of Co 2+ and Co 3+ [ 28 , 29 ]. The high-resolution XPS spectrum of the O element shows three peaks at 529.65 eV, 531.39 eV, and 532.24 eV in Figure 5 c. The first and second characteristic peaks correspond to lattice oxygen in metal oxides and hydroxyl radicals on the surface of materials, while the latter corresponds to adsorbed water on the surface [ 30 , 31 , 32 , 33 , 34 ].…”

Cycling stability of Fe2O3 nanosheets as supercapacitor sheet electrodes enhanced by MgFe2O4 nanoparticles

“…[26][27][28] In the eld of electrochemistry, MgFe 2 O 4 is not used enough, and some scholars have generated electrode materials with better cycling stability by combining metal oxides with MgFe 2 O 4 . [29][30][31] In this paper, Fe 2 O 3 /MgFe 2 O 4 materials were synthesised in one step using a simple hydrothermal method and grown directly on nickel foam. Through electrochemical tests, we found that the Fe 2 O 3 /MgFe 2 O 4 sheet electrode has better cycling stability and multiplicative performance compared to the Fe 2 O 3 sheet electrode.…”

Spinel ZnCr2O4 nanorods synthesized by facile sol-gel auto combustion method with biomedical properties

“…Among many promising nanomaterials, spinel and spinel-like nanomaterials have been broadly considered in recent years due to their imperative properties in material science [ 12 – 15 ], resulting in versatile applications such as wastewater treatment [ 16 ], energy storage [ 17 ], photocatalytic [ 18 , 19 ], organic transformations [ 20 ] and nanomedicine [ 21 , 22 ]. Together with ternary spinel oxide materials, zinc chromite nanoparticles (ZnCr 2 O 4 NPs) have attracted interest owing to their special applications in the fields of photocatalysis [ 23 ], sensing [ 24 ], organic transformation [ 25 ], and superconductors [ 26 ].…”
