PdNi-coated manganite nanorods as catalyst for electrooxidation of methanol in alkaline medium

Synthesis of mesoporous PtCu film modified with Ru submonolayer as catalyst for methanol electrooxidation.

A mesoporous PtCu catalyst modified with a Ru submonolayer is successfully synthesized by a facile electrochemical process of electrodeposition, dealloying and Ru underpotential deposition. The material has a large specific surface area comparable to nanoparticles (11 m(2) g(-1)) and exhibits a promising catalyst activity for the methanol oxidation reaction.

Remarkable support effect of SWNTs in Pt catalyst for methanol electrooxidation

Carbon nanotubes have been proposed as advanced metal catalyst support for electrocatalysis. In this work, different carbon support materials including single-walled carbon nanotubes (SWNTs), multi-walled carbon nanotubes (MWNTs) and XC-72 carbon black, were compared in terms of their electrochemical properties using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The ...

Methanol and CO electrooxidation

The methanol oxidation reaction has been the subject of a large number of studies in the past.[1, 2] Early work revealed a complex reaction mechanism,[3–6] indicating the electrocatalysis of methanol oxidation as the most difficult task in the realization of a direct methanol fuel cell (DMFC). Several metal catalysts were proposed for the reaction, most of them based on modifications of Pt with...

A Strategy for Fabricating Porous PdNi@Pt Core-shell Nanostructures and Their Enhanced Activity and Durability for the Methanol Electrooxidation

Three-dimensionally (3D) porous morphology of nanostructures can effectively improve their electrocatalytic activity and durability for various electrochemical reactions owing to big surface area and interconnected structure. Cyanogel, a jelly-like inorganic polymer, can be used to synthesize various three-dimensionally (3D) porous alloy nanomaterials owing to its double-metal property and part...
