Three-Dimensional Hierarchical Flower-Like Fe3O4 Porous Microstructure Decorated with Au Nanoparticles: Synthesis and Application for Sensitive Electrochemical Detection of Chloramphenicol

Synthesis of hierarchical binary core‐branch nanocomposite of carbon microspheres@α‐Fe2O3 for enhancing electrochemical behavior

“…To overcome these drawbacks, various functional nanostructured materials with excellent adsorption, catalytic performances, and high electrical conductivity could be used to modify the electrodes. [6][7][8][9] Hierarchical core-branch nanostructured materials such as metal oxide/metal, metal oxide/metal oxide, [10][11][12][13] metal oxide/metal hydroxide, [14,15] and carbon materials/metal oxide [16,17] that have received increasing attention because of their high conductivity, large specific surface area, and numerous adsorptive sites. In order to increase the electron transfer reaction between the electrolyte and work electrode interface, hybrid corebranch nanostructure materials with the synergistic effects of combined materials are used to modify electrodes.…”
