Highly dispersed platinum nanoparticles on carbon nanocoils and their electrocatalytic performance for fuel cell reactions
Highly graphitic carbon nanocoils (GCNC) were synthesized through the catalytic graphitization of carbon microspheres obtained by the hydrothermal carbonization of different saccharides (sucrose, glucose and starch) and were used as a support for Pt nanoparticles. The Pt nanoparticles were deposited by means of a polymer mediatedpolyol method. The Pt catalysts were characterized both physically...
متن کاملElectrocatalytic 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...
متن کاملCore–shell titanium dioxide /carbon nanofibers decorated nickel nanoparticles as supports for electrocatalytic oxidation of ethanol
Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...
متن کاملA cheap and an efficient electrode for electrocatalytic oxidation of methanol with nickel particles dispersed into sodium dodecyl sulfate modified carbon paste electrode
A sodium dodecyl sulfate modified carbon paste electrode (SDS/CPE) was developed in this work based on the surface modification method. The modified electrode was prepared by immersing SDS/CPE in a nickel nitrate solution. This electrode showed a strong accumulation ability toward nickel ions. Then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 V (vs. ...
متن کاملRemarkable 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 ...
