Low‐cost and high‐performance catalysts are of great significance for electrochemical water splitting. Here, it is reported that a laser‐synthesized catalyst, porous Co0.75Ni0.25(OH)2 nanosheets, is highly active for catalyzing overall water splitting. The porous nanosheets exhibit low overpotential...
