Activity of carbon-encapsulated Ni12−xFexP5 catalysts for the oxygen evolution reaction
Abstract
Rational design of efficient, earth-abundant, and durable electrocatalysts to accelerate the oxygen evolution reaction (OER) is critical for hydrogen ion by water electrolysis. In the present work, nanostructured Ni<sub>12−<i>x</i></sub>Fe<i><sub>x</sub></i>P<sub>5</sub> (<i>x</i> = 1.2, 2.4, 3.6) OER electrocatalysts synthesized by a colloidal method is reported. For <i>x</i> = 1.2, an alloy of Ni, Fe, and P is formed. For <i>x</i> = 2.4 or <i>x</i> = 3.6, a core-shell NiFeP@Fe<sub>3</sub>O<sub>4</sub> structure is formed. The nanoparticles are encapsulated in a self-generated carbon layer. The carbon layer is formed during synthesis from synthesis residues. The carbon-encapsulated Ni<sub>9.6</sub>Fe<sub>2.4</sub>P<sub>5</sub> catalyst offers the outstanding mass activity of 0.1 A mg<sup>−1</sup> and overpotential of 220 mV at 10 mA cm<sup>−2</sup>, assigned to a combination of enhanced electrical conductivity provided by the carbon shell, a large surface area, and a high specific catalytic activity. Post-mortem characterization indicates that the carbon encapsulation remains intact under conditions of the OER.
