[en] Highlights: • We reported a sample of NiSe@CoOOH/NF with core-shell nanostruture and high BET area by a facile approach for the first time. • The unique structure of the NiSe core and the coating with CoOOH nanosheets may improve the structural stability and accelerate fast electron transfer benefit to fast transportation of electron. • The NiSe@CoOOH NWs/NF possesses the advantages of large abundance, efficient electrocataly and good durability toward OER. - Abstract: 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.
