Surfactant-assisted Hydrothermal Synthesis of CoFe2O4 Nanostructures and Their Application in the Oxygen Evolution Reaction
Materials letters(2023)
摘要
In the present work, nanostructured CoFe2O4 (CFO) was successfully grown on Ni foam via a facile hydrothermal route using CTAB (cetyl trimethyl ammonium bromide), SDS (sodium dodecyl sulfate) and HMTA (hexamethylenetetramine) as surfactants, referred to as CFO-C, CFO-S and CFO-H, respectively. The structural, morphological, and electrochemical properties of the as-synthesized electrocatalysts were systematically studied. The interconnected nano-flakes-like structure of CFO-H facilitates faster reaction kinetics. Therefore, the CFO-H electrocatalyst exhibited higher OER performance with a lower overpotential of 343 mV at a current density of 10 mA cm-2 and a Tafel slope of 88.3 mV dec-1. All the electrocatalysts exhibited exceptional long-term stability for up to 25 h.
