Phosphorus-doped nickel-iron hydroxides/Mxene for efficient electrochemical water oxidation

NiFeP/Ti 2 C@NF was synthesized from a hydrothermal process and chemical conversion, and exhibited a low overpotential of 177 mV at j = 50 mA cm −2 , a low Tafel slope of 56 mV dec −1 , and a very competitive stable activity in alkaline electrolyte.
