Abstract
A method of preparing a platinum-based alloy catalyst includes preparing a carbon-supported platinum-based alloy catalyst for a fuel cell that may be mass-produced and has high activity and high durability by using an aqueous ozone treatment method.
Claims18
A method of preparing a platinum-based alloy catalyst, the method comprising:
- a first step of preparing a first composite by coating a Pt/C catalyst, obtained by supporting platinum on a carbon support, with an organic polymer;
- a second step of preparing a second composite by mixing the first composite and a transition metal precursor;
- a third step of performing a heat treatment on the second composite;
- and
- a fourth step of performing an aqueous ozone treatment on the heat-treated second composite.
