Abstract

Herein, NiFeP/Ti₂C@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, proposing a strategy for efficient OER and overall water splitting.
