Abstract

The invention relates to a preparation method of a double-effect oxygen electrode catalyst, in particular to the preparation method of a regenerable fueling battery oxygen electrode catalyst taking Pt as a basis. The method comprises the following steps: directly mixing a certain amount of H2IrCI6 and H2 PtCl6 into an organic solvent; adjusting the proportion of the H2IrCI6 and the H2 PtCl6; dripping the mixture onto a conductive matrix; and preparing an IrO2 Pt efficient catalyst through the thermal decomposition method, thereby not only the oxygen-evolution catalytic activity of the catalyst can be greatly improved, the electric potential can be reduced, and the availability of the catalyst is improved, but also the preparation process is simple, and no impurity enters; the prepared product can also be used for cathodic and anodic catalysts for other fuel batteries and other fields such as gas reforming, organic matter schizolysis, pollutant treatment, seawater electrolysis, and the like.
