Facile synthesis of nitrogen doped carbon decorated NiFe2O4 with enhanced OER performance

High performance, durable and affordable electrocatalyst for Oxygen Evolution Reaction (OER) is of great importance for tenable hydrogen production via water electrolysis. Although spinel oxide-based electrocatalysts (AB2O4, A, B = metal) represent a class of promising candidates for OER, their intrinsically poor electrical conductivity impacts their electrochemical performance. To overcome these bottlenecks, heteroatom-doped carbon structures can be used to improve the conductivity, adjust the electronic structure, durability and also boost the charge transfer, leading to enhanced electrochemical water oxidation [1]. In this work, a selection of nitrogen doped carbon decorated NiFe2O4 composites derived of polydopamine for OER in alkaline medium have been investigated.
