Etching oxide overlayers of NiFe phosphide to facilitate surface reconstruction for oxygen evolution reaction
文献摘要：
Transition-metal phosphides have been of concern as efficient electrocatalysts for oxygen evolution reaction(OER)due to its high con-ductivity and earth-abundance reserves.However,oxide overlayers formed on their surface by spontaneously atmospheric oxidation are usually neglected,thus confusing the establishment of structure-performance relationship.Herein,we successfully etched the oxide overlayers of NiFe phosphide(NiFeP)by a dielectric barrier discharge(DBD)plasma technique,aiming to reveal the influence of the oxide overlayers on its electrocatalytic performance for OER.It is found that etching the oxide overlayers can accelerate the surface reconstruction process of NiFeP and facilitate the formation of metal hydroxides,which are key intermediate phases for OER.Consequently,the etched NiFeP-DBD material shows remarkably enhanced OER activity with an overpotential of 265 mV at a current density of 10 mA cm-2.The finding of this work probably brings a significant impact to understand the structure-performance relationship of metal phosphide in electrooxidation reaction.
