Porous N-doped carbon with confined Fe-doped CoP grown on CNTs for superefficient oxygen evolution electrocatalysis

Herein, Fe-doped CoP nanoparticles (Fe-CoP NPs) encapsulated in porous N-doped carbon (PNC)/carbon nanotubes (CNTs) have been successfully synthesized. The Fe doping and confined structures resulted in enhanced charge transfer and improved active sites for intermediates adsorption. The obtained Fe-CoP@PNC/CNTs materials exhibited superefficient OER performance.
