Abstract

The development of highly efficient water oxidation electrocatalysts made of low-cost and earth-abundant elements is a prerequisite. Sluggish kinetics in the reaction of water splitting is the major obstacle. Herein, we report the fabrication of a robust catalyst for the oxygen evolution reaction (OER) based on the hybrid of N-doped graphene coupled metallic NiSe₂ pyramids (NG/NiSe₂/NF). The reaction kinetics has greatly increased due to the synergistic effects of the two components providing enhanced electroconductibility and increased active sites. The NG/NiSe₂/NF electrode exhibits superior water oxidation ability and cycle stability. This approach opens ways to design effective oxygen evolution electrodes.
