文摘
- •
Nanocrystalline CoP is obtained by gas phosphidation of electroplated Co species.
- •
The CoP catalyst exhibits a Tafel slope (30.1 mV/dec) comparable to Pt in acids.
- •
The CoP catalyst shows a Tafel slope of 42.6 mV/dec in basic solutions.
- •
The high HER activity is owing to its large surface area and active site density.
