제목 | Evaluation of synergetic effect on advanced electrocatalytic properties of Iron Nickel Nitride@rGO hybrid composite for oxygen evolution reaction |
초록 | In water splitting, oxygen evolution reaction (OER) is important process because high overpotential is required to achieve the current density for the reaction. Transition-metal nitrides (TMN) used as electrocatalyst materials for OER are being recently studied because of high yield, easy operation, and excellent catalytic activity by high electrical conductivity. In particular, iron-nickel nitride has very high catalytic activity due to owing to high electro-catalytic and high stability. Reduced graphene oxide (rGO) known as 2 Dimensional (2 D) carbon materials is extensively used as supporting material owing to high conductivity, large theoretical specific surface area, and excellent stability. In this study, we successfully synthesized Fe2Ni2N/rGO hybrid composite for OER electrocatalyst material through two-step process with hydrothermal method and annealing. The morphology of precursor and Fe2Ni2N/rGO hybrid composite was analyzed by FE-SEM. The crystallinity of sample was confirmed by XRD. GO was confirmed by Raman spectroscopy. And the components of as-prepared precursor were measured by FT-IR spectra. Furthermore, we analyzed electrochemical properties of synthesized sample. |
