Cu2O@Fe–Ni3S2 nanoflower in situ grown on copper foam at room temperature as an excellent oxygen evolution electrocatalyst. Issue 82 (15th September 2020) - Wu, Li Li
Abstract : A 3D/2D core–shell Cu2 O@Fe–Ni3 S2 nanoflower is prepared at room temperature through an etching precipitation strategy for enhanced electrochemical water oxidation. Abstract : Herein, we have synthesized successfully a three-dimensional/two dimensional (3D/2D) core–shell Cu2 O@Fe–Ni3 S2 nanoflower on copper foam at room temperature. Remarkably, by virtue of rich active sites and vacancies, large surface area, high conductivity and close contact with the electrolyte, the Cu2 O@Fe–Ni3 S2 catalyst exhibits superior stability and oxygen evolution reaction performance.
