Catalyst material |
| 摘要 |
An improved catalyst material is derived from a precious metal-containing macrocyclic compound precursor, which contains precious metal in zero oxidation state. The material may be produced by activating the compound, for example by a voltage sweep. The material offers useful improvements in activity and resistance to de-activation, when used as a fuel cell catalyst.
