内容記述 |
The enhancement in durability of Pt nanoparticles modified by nanostructured RuO2 was studied using a model electrode consisting of vacuum deposited Pt on single crystalline RuO2 nanosheets coated on highly oriented pyrolytic graphite (HOPG) surface with sub-monolayer coverage. Atomic force microscopy images showed that Pt on HOPG aggregated and tended to form 3-dimensional islands. On the other hand, Pt formed a well-defined, 2-dimensional over-layer on the RuO2 nanosheet surface. In-situ atomic force microscopy images showed that deposited Pt on the HOPG surface readily dissolved and easily migrated with potential cycling in sulfuric acid, while no such phenomena could be observed on the RuO2 nanosheets. The results indicate that RuO2 nanosheet has a strong affinity toward Pt, namely strong metal-support interaction for Pt, which can be considered as one of the reasons for the enhanced durability of Pt/C modified by RuO2 nanosheets. |
