Preparation of carbon molecular sieve-supported Pt catalysts covered with silica layers and its application in PEMFC |
| 초록 |
Pt-carbon molecular sieve with regular nano-structure was successfully prepared via zeolite Y as template where Pt was incorporated into regular nano-structured carbon molecular sieve by polyol method. The durability test for Pt catalyst covered with silica layer was conducted by repeating potential cycling experiment upto 1200cycles and compared with test Pt-CMS without silica layer.Regular nano-structure of Pt-CMS and the thickness of silica layer were indentified by transmission electron micrograph(TEM), BET and XRD. The both electrodes were fabricated by brush coating method using both Si02-Pt-CMS and Pt-CMSand the cell performance was conducted and compared. |
