چکیده
Abstract Mass activity and long-term stability are two major issues in current fuel cell catalyst designs. While supported catalysts normally suffer from poor but show high mass activity, unsupported tend to perform better the first point while showing deficits latter one. In this study, a facile synthesis route towards self-supported metallic electrocatalyst nanoarchitectures with both aspects mind is outlined. This procedure consists of palladium seeding step ion track-etched polymer templates followed by nickel electrodeposition template dissolution. With strategy, free-standing nanowire networks which contain nanoparticles only their outer surface obtained. These tested anodic half-cell measurements for demonstrating capability oxidising methanol alkaline electrolytes. The results electrochemical experiments that new more tolerant concentrations (up $${5}\,\hbox{mol}\,\hbox{L}^{-1}$$ 5 mol L - 1 ) than commercial carbon nanoparticle provides much during potential cycling.

ZnO Nanowire-supported Ag Catalyst for Methanol Steam Reforming
Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...

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.
متن کاملMethanol-Tolerant Platinum-Palladium Catalyst Supported on Nitrogen-Doped Carbon Nanofiber for High Concentration Direct Methanol Fuel Cells
Pt-Pd catalyst supported on nitrogen-doped carbon nanofiber (N-CNF) was prepared and evaluated as a cathode electrode of the direct methanol fuel cell (DMFC). The N-CNF, which was directly synthesized by the catalytic chemical vapor deposition from acetonitrile at 640 °C, was verified as having a change of electrochemical surface properties such as oxygen reduction reaction (ORR) activities and...
