摘要：

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.
