Far from equilibrium: This thesis provides a deep mechanistic analysis of the electrooxidation of methanol when the system is kept far from the thermodynamic equilibrium. Under an oscillatory regime, interesting characteristics between the elementary reaction steps were observed. We were able to elucidate the effect of the intrinsic drift in a potential time-series responsible for spontaneous t...

Electronic Modifi cation Effects Induced by Fe in Pt-Ru-Fe Ternary Catalyst on the Electrooxidation of CO/H2 and Methanol Taeyoon Kim, Koichi Kobayashi 2* , Tetsuo Take 2 and Masayuki Nagai 2 1 Department of Chemistry and Energy Engineering, Tokyo City University (Tokyo 158-8557, JAPAN) 2 Research Center for Energy and Environmental Science, Advance Research Laboratory, Tokyo City University (T...

In this work, Pt, Fe and Co nanoparticles were prepared by chemical reduction of the metal salts in chitosan as the support. NaBH4 was used as the reducing agent Pt-Fe, Pt-Co and Pt-Fe-Co-chitosan nanocomposites were synthesized and characterized by UV–Vis spectra and Transmission electron microscopy images. GC/Pt-chitosan, GC/Pt-Co-chitosan, GC/Pt-Fe-chitosan and GC/Pt-Co-Fe-chitosan electrode...

Electrooxidation of methanol, ethanol, and formic acid was studied on three platinum-containing electrocatalysts: PtCu/C, Pt/(SnO2/C), Pt/C, Pt content being about 20 wt%. In all reactions, the integral specific activity catalysts, estimated from results cyclic voltammetry, grows in Pt/C < Pt/(SnO2/C) PtCu/C row. The influence reagent nature subjected to electrooxidation is manifested both d...

A novel non-precious multiwalled carbon nanotubes (CNTs)—supported metal oxide electrocatalyst was developed for methanol electrooxidation in alkaline medium. The catalyst was fabricated by simultaneous electrodeposition of copper-cobalt-nickel ternary nanostructures (CuCoNi) on a glassy carbon electrode (GCE) modified with CNTs. The proposed electrode was characterized using X-ray diffraction ...
