AbstractTransition metal nitrides are of considerable interest for energy conversion and storage applications. Given this, synthesis of nanostructured 3D transition metal nitrides is of contemporary interest. Here, a hard templating simple and efficient pathway to synthesize 3D ordered-mesoporous ternary nitrides NiCo2N is reported using the mesoporous silica KIT-6 hard template. Benefitting from its large surface area and accessible pores, uniform shape, and enhanced infiltration capacity for electrolyte, mesoporous NiCo2N demonstrates superior electrode performance for oxygen evolution reaction (OER) in alkaline medium. As-synthesized mesoporous ternary nitride NiCo2N shows desirable performance with very low overpotential (289 mV), and yields approximate to 10 mA cm(-2) geometric current density. This is lower than the values of IrO2 and that of mesoporous binary nitrides CoN and Ni3N electrocatalysts. NiCo2N shows a small Tafel slope and smallest semicircle. Moreover, as-synthesized NiCo2N exhibits low loss of activity after 10 h test for OER in alkaline solution. This work explores a promising way to produce OER electrocatalyst Co-Ni-based ternary nitrides for water splitting applications.
