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

Abstract

Different morphology CoFe2O4 nanoparticles (nano random particles, nanospheres, solid nanocubes) are successfully synthesized via a facile one‐step method, by controlling the amount of the surfactant. The solid nanocube morphology CoFe2O4 is annealed at 350 °C to form porous and hollow structure. The interesting porous hollow nanostructural CoFe2O4 has excellent electrochemical properties.

Biodegradation of Oxide Nanoparticles in Apoferritin Protein Media: A Systematic Electrochemical Approach

“…Regarding the impedance evolution, the modulus value at 0.01 Hz was recorded at different immersion times to extract information about the resistance associated with the charge transfer process on the oxide surface in an apoferritin environment (Figure 5e). [ 78 ] In the case of CFO nanoparticles at pH 7, an important increase in resistance after 2 h is observed (565 kΩ cm 2 ), followed by a slight decrease in the impedance modulus. Then, this value gradually increases up to 48 h (569 kΩ cm 2 ).…”
