HOLLOW PLATINUM NANOPARTICLES FOR FUEL CELLS |
| 摘要 |
The present invention relates to hollow platinum nanoparticles with a diameter comprised between 3 and 20 nm which comprise a first central cavity and optionally at least one second cavity at the periphery of the first cavity, the shell of which is dense and single-crystal with a thickness comprised between 0.2 and 5 nm. The invention also relates to a method for manufacturing such nanoparticles, as well as to their use as an electrocatalyst in fuel cells. |
