A direct method to prepare nanometre catalyst of positive electrode for methyl alcohol fuel battery is to add strong oxidant to a mixed solution of manganese nitrate and some other metal nitrate, to coat them on the graphite electrode to have catalyst precursor produced, then to prepare the non-platinum nanometre catalyst of metal ion-doped manganese dioxide with carbon as a carrier by thermolytic reaction of the in-situ precursor. The prepared catalyst has the advantages of high electrical catalytic activity of methyl alcohol, high performance to protect against CO poison and low price, and it can lower the battery manufacturing cost effectively as well as can raise the entire electrical property of the battery so that the price performance and the market competitive edge of the battery are enchnaced effectively.
