摘要: A method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.

摘要: An Ag/MnyOx/C catalyst is disclosed, wherein MnOyx is one of Mn3O4 and MnO, or the mixture of Mn3O4 and MnO, or the mixture of Mn3O4 and MnO2 with the mass content of MnO2 in the mixture of Mn3O4 and MnO2 being 0.01-99.9%. The catalyst is obtained by pyrolyzing AgMnO4 at a high temperature. The preparation method comprises two steps: (1) preparing AgMnO4 crystal as the precursor; (2) preparing the Ag/MnyOx/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.
