Facile Strategies for Introduction of Protective N-doped Carbon Layers on Highly loaded Platinum based Catalysts for Fuel Cell Durability |
| 초록 |
To increase the durability of highly loaded platinum- and platinum-nickel alloy catalysts, a nitrogen-doped carbon layer was introduced on the catalyst surface through dopamine coating process. Most previous studies have introduced a protective shell on a 20 wt% metal catalyst on support. In these cases, the distance between the metal nanoparticles is long because the total amount of the metal is small compared to the support. Therefore, metal agglomeration is rare during the high temperature heat treatment used to form the carbon layer. However, highly loaded catalysts are often used in practical fuel cell devices to reduce the volume of the electrodes; therefore, the smaller distance between metal nanoparticles means that they can quickly agglomerate, even at low temperatures where the carbon shell is not well formed. We herein report the introduction of a nitrogen-doped carbon shell by dopamine coating on the surfaces of highly-loaded platinum- and platinum-nickel alloy catalysts |
