One-step accurate synthesis of shell controllable CoFe2O4 hollow microspheres as high-performance electrode materials in supercapacitor

Facile Synthesis of Morphology Controllable CoFe2O4 Particles as High‐Performance Electrode Materials

“…The solution with a certain concentration of CTAB will generate microspherical micellae. In the solution, the hydrophilic CTA + groups, point to the outer surface of the micellae, while the hydrophobic ends point to the inner . Owing to all crystal being coordinated by CTAB capping ligands and showing saturated surface coverage, thus that directing the nuclei to grow isotropically along the three crystallographic axes, resulting in 0D nanosphere…”

Iron‐Based Supercapacitor Electrodes: Advances and Challenges

“…[123][124][125][126] These binary metal oxides containing one or more electrochemical active/inactive ions can exert the synergistic effect of pure oxides and have better electrical conductivity than pristine mental oxides.

“…[124] Yu et al reported that NiFe 2 O 4 nanoparticles directly grown on flexible carbon cloth by a surfactant-assistant hydrothermal method showed remarkable specific capacitance (1135.5 F g −1 in 1 m H 2 SO 4 ) and excellent rate capability (more than 80% retention as the current density increases from 2 to 100 mA cm −2 ). [123] The number of shells can be controlled by adjusting the ratio of water to ethanol. Notably, multi-shelled CoFe 2 O 4 hollow microspheres with tunable layers were prepared via a facile one-step process using cyclodextrin as a template.…”

Synthesis of Single‐Component Metal Oxides with Controllable Multi‐Shelled Structure and their Morphology‐Related Applications

“…The carbonaceous microspheres originate from the polymerization and carbonization of glucose and become solid foundation for the preparation of multi‐shelled hollow spheres with diverse compositions and structures through sequential templating approach (Figure ). In addition to glucose, a variety of carbon sources including but not limited to sucrose, cyclodextrin, fructose and amino acid have been proved to be feasible raw materials for preparation of carbonaceous microspheres. Apart from the carbonaceous microspheres template, polymer particles and metal organic frameworks are also developed as rational designed templates.…”
