Formation of Prussian‐Blue‐Analog Nanocages via a Direct Etching Method and their Conversion into Ni–Co‐Mixed Oxide for Enhanced Oxygen Evolution

Novel Ni–Co-Prussian-blue-analog nano­cages consisting of pyramid-like walls were prepared via a facile chemical etching process with ammonia at room temperature. After annealing in air, the derived Ni–Co mixed oxide nanocages exhibit enhanced electrocatalytic activity and excellent stability toward the oxygen-evolution reaction.
