Design of NiCo₂O₄@NiMoO₄ core–shell nanoarrays on nickel foam to explore the application in both energy storage and electrocatalysis

Abstract

NiCo2O4@NiMoO4 core-shell nanowires (NCNMW) and nanosheets (NCNMS) with high electrochemical capabilities were synthesized using a simple two-step hydrothermal reaction, together with a calcination process. As active electrode material, all of...

A Mesoporous Magnetic Fe3O4/BioMOF-13 with a Core/Shell Nanostructure for Targeted Delivery of Doxorubicin to Breast Cancer Cells

“…53 From the aspect of structural stability and strength, covalent binding that is formed in the core/shell architecture is highly preferred to the interactions mentioned for the surface composite architecture. 54 Therefore, the core/shell structure has been considered as the optimal architecture for preparation of the Fe 3 O 4 /Bio-MOF-13 drug nanocarrier.…”

“…In Fe 3 O 4 /Bio-MOF-13 surface composite structure, the Fe 3 O 4 NPs are incorporated into the voids and onto the surface of Fe 3 O 4 /Bio-MOF-13, held by metal–oxygen, metal–metal, and hydrogen-bond (H-bond) interactions . From the aspect of structural stability and strength, covalent binding that is formed in the core/shell architecture is highly preferred to the interactions mentioned for the surface composite architecture . Therefore, the core/shell structure has been considered as the optimal architecture for preparation of the Fe 3 O 4 /Bio-MOF-13 drug nanocarrier.…”

Recent Progress in the Core-Shell Nanostructures of the NiMoO4-Based Composite Materials for Supercapacitor Applications: A Comprehensive Review

“…The areal and mass-specific capacitances were 7.55 Fcm −2 and 1242 Fg −1 , respectively, at 10 mAcm −2 . By changing the reaction time, nanosheets and nanoplates of NiMoO4 were grown onto the backbone of NiCo2O4 (nanowires and nanosheets), and the electrode performance was considerably good [74][75][76]. For NiMoO4, it is clear that the sheet-like morphology can be observed at a prolonged reaction time.…”

Richly electron-deficient BCxO3−x anodes with enhanced reaction kinetics for sodium/potassium-ion batteries

“…Notably, owing to the electron-deficient nature of boron atoms, doping boron could effectively activate the inert electronic structure in the carbon skeleton, resulting in remarkable charge transfer between sodium/potassium and the substrate. [28][29][30][31][32][33][34][35][36] For instance, Barone et al 37 initiated the evaluation of the electrochemical properties of hexagonal BC 3 as a robust electrode material for PIBs through dispersion-corrected density functional theory. The results indicate that the intercalated hexagonal BC 3 (M x BC 3 , 0 o x r 2) exhibits the maximum stable capacity associated with the large gravimetric capacities of 572 mA h g À1 for Na and 858 mA h g À1 for K, a weak ion migration barrier, and small opencircuit voltage variation.…”
