A facile strategy for the synthesis of NiSe@CoOOH core-shell nanowires on nickel foam with high surface area as efficient electrocatalyst for oxygen evolution reaction

In this article, we describe a NiSe@CoOOH core-shell nanostructure nanowires supported on nickel foam(NiSe@CoOOH NWs/NF) have been successfully synthesized by a facile approach for the first time. The NiSe@CoOOH NWs/NF has been confirmed by XRD, SEM images, TEM images, XPS, EDX and HRTEM. The NiSe@CoOOH NWs/NF, as a 3D oxygen-evolving and nonprecious-metal catalyst, shows high catalytic performance for oxygen evolution reaction.
