Abstract
We report the advancement of the catalytic activity for the oxygen evolution reaction using an orthogonal procedure to fabricate an α cobalt hydroxide hydrotalcite-like compound using rock salt and its transformation to a translucent single-layer cobalt hydroxide nanosheet by liquid phase exfoliation. The exfoliated single-layer nanosheet exhibited a remarkable mass activity of 153.8 A g−1 and a turn over frequency of 1.46 × 10−1 s−1 at 350 mV overpotential.
