A highly efficient FeP/CeO2–NF hybrid electrode for the oxygen evolution reaction

Abstract

Transition metal phosphides have been proven as highly efficient electrocatalysts. In this study, a FeP/CeO2–NF hybrid electrode was prepared by a simple electrodeposition and high-temperature phosphorization method. The electrode exhibits outstanding performance for the OER with an overpotential of only 245 mV at a current density of 100 mA cm−2, a Tafel slope as low as 39.1 mV dec−1 and an excellent durability for 50 h at a current density of 10 mA cm−2 in an alkaline solution. Such significant high performances are attributed to a combined effect of the excellent electron conductivity of CeO2 and unique uneven columnar structure of the electrode.
