Abstract

We report a pyrolysis reduction method to prepare highly uniform dispersed CoNi_x nanoparticles embedded in nitrogen-carbon frameworks. With an appropriate value of Ni/Co, the obtained CoNi_0.37-CN catalyst exhibited excellent properties and stability in electrocatalytic oxygen evolution, which are superior to those of the commercial IrO₂.
