Oxygen‐vacant nanocrystalline MnO 2 has been prepared by the simple process of annealing pristine oxide in Ar or O 2 . Both experimental and computational studies indicate that the catalytic activity of MnO 2 towards oxygen reduction is enhanced by introducing a modest concentration of oxygen vacancies.
