Method for producing a platinum-based alloy catalyst |
abstract |
The present invention relates to a method for manufacturing a method for manufacturing a platinum-based alloy catalyst, simplifying the manufacturing process by omitting the process of preparing a transition metal precursor solution, and improving the performance of the catalyst by increasing the degree of alloying through heat treatment. The present invention comprises the steps of dispersing a carbon-based catalyst support in a polyol to prepare a carbon-based catalyst support solution; preparing a mixed solution by adding a platinum solution and a transition metal precursor powder to a carbon-based catalyst carrier solution and mixing at 40 to 100° C.; adding a pH adjusting agent to the mixed solution; applying a temperature to the mixed solution to which the pH adjusting agent is added to reduce it to a platinum-based alloy containing a transition metal and supporting it on a carbon-based catalyst carrier; washing and drying the mixture solution containing the platinum-based alloy supported on the carbon-based catalyst carrier; And heat-treating the dried platinum-based alloy catalyst at 400 to 500 ℃; provides a method for producing a platinum-based alloy catalyst comprising a. |
