Preparation of molybdenum phosphide-cobalt phosphide on electrospun carbon nanofibers as monolithic electrocatalyst for efficient hydrogen production
Preparing phosphide electrocatalysts with both excellent intrinsic activity and abundant active sites toward efficient hydrogen production is beneficial for the realization of the hydrogen society.In this study,we utilized combined methods of electrochemical deposition and chemical vapor deposition to construct a cobalt phosphide-molybdenum phosphide on an electrospun carbon nanofibers substrate as monolithic electrocatalyst(Mo-Co-P/CNFs)with excellent hydrogen evolution performance.The Mo-Co-P/CNFs catalyst which can be directly used as a working electrode,not only exhibits improved intrinsic activity but also has highly abundant active sites,realizing a current density of 100 mA·cm-2 under over-voltage of only 70 mV in a 1 M KOH electrolyte.This study is expected to offer useful references for the preparation of high-performance phosphide catalysts.
