Reasonable optimization of the crystal structure and composite is an effective way to enhance electrocatalytic activity transition metal oxides. Herein, we report a strategy fabricate Fe-doped amorphous CoOx (a-CoyFezOx) as oxygen evolution reaction (OER) catalyst by facile reduction at room temperature. In 1 M KOH electrolyte, optimized a-Co2.5Fe0.5Ox shows best OER activity. It only requires 280 mV overpotential achieve current density 10 mA cm–2 with Tafel slope 39.9 dec–1, which even...
The octahedral sites in Co3O4 usually possess better oxygen evolution reaction (OER) activity, which have been identified as the active sites. Atomic cationic vacancy defects can elicit localized electron redistribution to regulate electronic structure of host materials. In this paper, nanosheet arrays with vacancies at (Vx-Co3O4) synthesized by a facile three-step process. Density functional theory (DFT) computational results further indicate that increase number electrons per Co atom and...
