Abstract
The development of efficient and durable bifunctional electrocatalysts for oxygen evolution reaction (OER), still poses huge challenges. Herein, we utilize a facile hydrothermal method to synthesize a novel IrNi nanocrystals. In particular, the electronic structure is altered when a portion of the iridium atom is replaced by a Ni atom, which causes the center of the d band to shift downward, favoring the catalytic reaction. The overpotentials for OER of 273 mV at a current density of 10 mA cm−2, exceed the capabilities of commercial Ir catalysts. The alloying of Ir with Ni reduces the adsorption energy of oxygen intermediates to achieve a fast oxygen evolution reaction. This work highlights a potentially powerful strategy toward the general synthesis of novel, Ir-based alloy as highly active and durable bifunctional electrocatalysts for high-performance electrochemical overall-water-splitting devices.
