Hierarchical hollow nanocubes based on ultra‐thin CoFe‐layered double hydroxide (CoFe−LDH) nanosheets have been prepared. The obtained CoFe−LDH hollow nanocubes could effectively catalyze water oxidation at a low overpotential of 270 mV @ 10 mA cm −2 , low Tafel slope of 58.3 mV dec −1 and show a long‐term stability in alkali.
