COMPARATIVE STUDY OF OMC, MWCNT AND VULCAN XC-72 AS CARBONACEOUS SUPPORTS OF PT CATALYSTS FOR DIRECT ALCOHOL FUEL CELLS APPLICATIONS

摘要

High-activity Pt/C catalysts for MEOR, EOR, EGOR werernsuccessfully prepared using a polyol method. The differences in thernstructural properties of the OMC and MWCNT supports the catalyticrndetermine significantly the catalytic activity in the MOR, EOR andrnEGOR and durability of the support in acid media.The improve ofrnPt/OMC for alcohol oxidation reaction could be related to thernmesoporous structure of the support and higher tolerance torncarbonaceous intermediates, thus inhibiting the self-poisoning ofrncatalysts.
