An Ag/MnO/C catalyst is disclosed, wherein MnOis one of MnOand MnO, or the mixture of MnOand MnO, or the mixture of MnOand MnOwith the mass content of MnOin the mixture of MnOand MnObeing 0.01-99.9%. The catalyst is obtained by pyrolyzing AgMnOat a high temperature. The preparation method comprises two steps: (1) preparing AgMnOcrystal as the precursor; (2) preparing the Ag/MnO/C catalyst. The catalyst has advantages such as high oxygen reduction reaction (ORR) catalytic activity in an alkaline environment, good stability, abundant availability and low cost of raw materials, safety, non-toxicity and pollution-free, environmental friendliness, and adaptive capacity for massive production. The catalyst can be used as oxygen reduction catalyst in metal air fuel cell, alkali anion exchange membrane fuel cell and other alkaline environments.
