Hierarchical Pd-Sn Alloy Nanosheet Dendrites: An Economical and Highly Active Catalyst for Ethanol Electrooxidation

Hierarchical alloy nanosheet dendrites (ANSDs) are highly favorable for superior catalytic performance and efficient utilization of catalyst because of the special characteristics of alloys, nanosheets, and dendritic nanostructures. In this paper, we demonstrate for the first time a facile and efficient electrodeposition approach for the controllable synthesis of Pd-Sn ANSDs with high surface a...

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...

Carbon nanocoils as catalyst support for methanol electrooxidation: a DEMS study

Electrocatalytic properties of platinum catalyst for methanol electrooxidation enhanced by nafion-thionine ion-pair

Nafion (Nf)-thionine (Th) ion-pair as dispersant and second catalyst has been introduced in Pt catalyst for methanol electrooxidation and the resulting catalyst supported on carbon (NfThPt/C) has been investigated by electrochemical method. For the same loading mass of Pt, the peak current density of methanol oxidation on the NfThPt/C/graphite electrode is about 7.25 and 3.04 times as high as t...

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 ...
