Flexible direct synthesis of phosphorus-rich CoP₃ on carbon black and its examination in hydrogen evolution electrocatalysis

Abstract

The reaction of CoCl2 on carbon black with phosphorus yields crystalline CoP3 particles on a carbon. Low CoP3 (5–25 mol%) content is distributed on the carbon support and shows electrocatalytic hydrogen evolution activity similar to bulk CoP3.

“…Hydrogen is a popular choice of future energy material for transducing renewable energy to practically usable electricity with minimal greenhouse gas emissions. 1–4 In this flow of events, the hydrogen evolution reaction (HER) from abundant water is reckoned as a key step. Water electrolysis is looked upon as the primary pathway for industrial-scale HER, which is required to be executed at a rapid rate with low overpotential requirements.…”
