Deliberate Modification of Fe 3O 4 Anode Surface Chemistry: Impact on Electrochemistry
Abstract
Fe 3O 4 nanoparticles (NPs) with an average size of 8-10 nm have been successfully functionalized with various surface-treatment agents to serve as model systems for probing surface chemistry-dependent electrochemistry of the resulting electrodes. The surface-treatment agents used for the functionalization of Fe 3O 4 anode materials were systematically varied to include aromatic or aliphatic structures: 4-mercaptobenzoic acid (MBA), benzoic acid (BA), 3-mercaptopropionic acid (MPA), and propionic acid (PA). Both structural and electrochemical characterizations have been used to systematically correlate the electrode functionality with the corresponding surface chemistry. Surface treatment with ligands led to better Fe 3O 4 dispersion, especially with the aromatic ligands. Electrochemistry was impacted where the PA and BA-treated Fe 3O 4 systems without the -SH group demonstrated higher rate capability than their thiol-containing counterparts and the pristine Fe 3O 4. Specifically, the PA system delivered the highest capacity and cycling stability amongst all samples tested. Notably, the aromatic BA system outperformed the aliphatic PA counterpart during extended cycling under high current density, due to the improved charge transfer and ion transport kinetics as well as better dispersion of Fe 3O 4 NPs, induced by the conjugated system.
