Preparation 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...

CO-Tolerant Pt–BeO as a Novel Anode Electrocatalyst in Proton Exchange Membrane Fuel Cells

Commercialization of proton exchange membrane fuel cells (PEMFCs) requires less expensive catalysts and higher operating voltage. Substantial anodic overvoltage with the usage of reformed hydrogen fuel can be minimized by using CO-tolerant anode catalysts. Carbon-supported Pt–BeO is manufactured so that Pt particles with an average diameter of 4 nm are distributed on a carbon support. XPS analy...

Sn-doped TiO2 modified carbon to support Pt anode catalysts for direct methanol fuel cells

Catalyst supports are known to play important role in governing overall catalyst activity and durability. Here, a new type of SnO2eTiO2 solid solution (TixSn1-xO2) support was prepared via a solvothermal method with substitution of Ti4þ by Sn4þ in the TiO2 lattice. Furthermore, the TixSn1-xO2 was combined with conventional carbon black (Vulcan XC-72) to prepare a hybrid support (TixSn1-xO2eC) f...

Synthesis and characterization of Pt/graphene-CNTs electrocatalyst for direct methanol fuel cell

In the present work we report a facile method for the synthesis of Pt nanoparticles supported reduced graphene oxide (rGO) and multi-walled carbon nanotubes (MWCNTs) nanocomposite by an in-situ chemical reduction. The incorporation of MWCNTs to rGO leads to decrease in agglomeration between rGO sheets due to π – π interactions and higher loading of Pt nanoparticles. In this process, a mixture o...

High Pt Loading on Polydopamine Functionalized Graphene as a High Performance Cathode Electrocatalyst for Proton Exchange Membrane Fuel Cells

Morphology and size of platinum nanoparticles are a crucial factor in improving their catalytic activity and stability. Here, we firstly report the synthesis of high loading Pt nanoparticles on polydopamine reduced Graphene. The loading concentration of Pt (nanoparticles) NPs on Graphene can be adjusted in the range of 60-70%.With the insertion of polydopamine between Graphene oxide sheets, sta...
