Enhancing electrocatalytic oxygen reduction on MnO(2) with vacancies.
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.
