Bimetallic Oxide/Hydroxide Composite for Electrocatalytic Oxygen Evolution Reaction |
| 초록 |
Abstract : In this work, a bimetallic oxide/hydroxide composite, ZNDP-1, was synthesized for electrocatalytic oxygen evolution reaction (OER) using Zn(II) and Ni(II) precursors along with polyvinylpyrrolidone (PVP) and dopamine (DA). Microscopic studies showed the formation of ZnO and Ni(OH)2 in composite. The growth modification ability of PVP and adhesive property of polydopamine from DA were utilized to obtain a 3D interconnected structure. In alkaline medium, ZNDP-1 showed a low over potential of 170 mV (@10 mA cm-2 current density) and a Tafel slope of 90 mV dce-1 with significant stability for OER. The surface defects, porosity and synergism within metal centers caused such intriguing electrocatalytic activity. Keywords : Transition metals; bimetallic oxide/hydroxide composite; synergism; electrocatalysis; oxygen evolution reaction. |
