New Electrocatalysts for Fuel Cells
Approach • Study the kinetics of fuel cell electrode reactions on well-characterized model electrodes and high surface area fuel cell electrocatalysts using modern electroanalytical methods. • Study the mechanisms of the reactions using state-of-the art in-situ spectroscopes. • Use ultrahigh vacuum (UHV) methods of surface preparation and surface analyses to form tailored surfaces. • Synthesize...
متن کاملNanostructured Carbon Materials as Supports in the Preparation of Direct Methanol Fuel Cell Electrocatalysts
Different advanced nanostructured carbon materials, such as carbon nanocoils, carbon nanofibers, graphitized ordered mesoporous carbons and carbon xerogels, presenting interesting features such as high electrical conductivity and extensively developed porous structure were synthesized and used as supports in the preparation of electrocatalysts for direct methanol fuel cells (DMFCs). The main ad...
متن کاملSelf-assembled platinum nanoparticles on sulfonic acid-grafted graphene as effective electrocatalysts for methanol oxidation in direct methanol fuel cells
In this article, sulfonic acid-grafted reduced graphene oxide (S-rGO) were synthesized using a one-pot method under mild conditions, and used as Pt catalyst supports to prepare Pt/S-rGO electrocatalysts through a self-assembly route. The structure, morphologies and physicochemical properties of S-rGO were examined in detail by techniques such as atomic force microscope (AFM), transmission elect...

متن کاملPreparation and Characterization of Electrocatalyst Nanoparticles for Direct Methanol Fuel Cell Applications Using β-D-glucose as Protection Agent
In this study, the activity, stability and performance of carbon supported platinum (Pt/C) electrocatalyst in cathode and carbon supported Pt and ruthenium (PtRu/C) electrocatalyst in anode of direct methanol fuel cell (DMFC) were studied. The Pt/C and PtRu/C electrocatalysts were prepared by impregnation reduction method. The β-D-glucose was used as protection agent to reduce the particle size...
