CoFeP hierarchical nanoarrays supported on nitrogen-doped carbon nanofiber as efficient electrocatalyst for water splitting.

Developing high-efficient bifunctional electrocatalysts is significant for the overall water splitting. Bimetallic phosphides show great potential for the bifunctional hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalysts due to the excellent catalytic performance. Herein, the CoFeP two-dimensional nanoarrays successfully grown on nitrogen doped electrospun carbon nanofibers (CoFeP NS@NCNF) through template-directed growth and following phosphorization treatment.

A highly effective bifunctional catalyst of cobalt selenide nanoparticles embedded nitrogen-doped bamboo-like carbon nanotubes toward hydrogen and oxygen evolution reactions based on metal-organic framework.

Metal selenides as highly efficient bifunctional electrocatalysts were extensively applied to water-splitting technology. In present work, N-doped graphitized carbon wrapped CoSe nanoparticles (NPs) with in-situ grown bamboo-like carbon nanotube (CoSe@N/C-CNT) was successfully synthesized via a Co-Ade (Adenine) MOF-derived selenylation strategy. Each CNT was capped with CoSe NP, which not only effectively avoided self-agglomeration of CoSe NPs but also protected the CoSe NPs from electrolyte etching.
