Assembling pore-rich FeP nanorods on the CNT backbone as an advanced electrocatalyst for oxygen evolution

Electrocatalytic water splitting is a promising means for clean energy production. There is a great need to develop low cost, efficient and durable electrocatalysts for such purposes. Herein, we report a novel hierarchical nanostructure composed of FeP porous nanorods on CNT backbones. The directed growth of alpha-FeO(OH) nanospindles on CNTs was first realized via a bottom-up assembly, followed by phosphorization transformation. When evaluated for the electrocatalytic water splitting reaction, these hierarchical structures exhibited superior oxygen evolution performance due to their advantageous structural features.
