According to Yang Shao-Horn's principle, CoSe2 is a promising candidate as an efficient, affordable, and sustainable alternative electrocatalyst for the oxygen evolution reaction, owing its well-suited electronic configuration of Co ions. However, catalytic efficiency pure still far below what expected, because poor active site exposure yield. Herein, we successfully overcome disadvantage insufficient sites in bulk by reducing thickness into atomic scale rather than any additional...
