Photocatalytic methods for preparation of electrocatalyst materials
| DWPI Title: Producing method for electrocatalyst used for fuel cell, involves illuminating mixture of photocatalyst, reductant and metal compound to form metal particles by reduction of metal compound |
| Abstract: The invention relates to methods of preparing metal particles on a support material, including platinum-containing nanoparticles on a carbon support. Such materials can be used as electrocatalysts, for example as improved electrocatalysts in proton exchange membrane fuel cells (PEM-FCs). |
| Use: For producing an electrocatalyst used for fuel cell for e.g. automotive applications. |
| Advantage: Enhances effectiveness of electrocatalyst. |
| Novelty: The method involves illuminating a mixture of photocatalyst, reductant and metal compound to form metal particles (32) by reduction of the metal compound. The metal particles are supported on an electron-conducting carbon support material (34) to form an electrocatalyst. |
