TLDR
In this paper, the electrocatalytic oxidation of methanol at a glassy carbon electrode modified by a thin film of poly(o-aminophenol) (PoAP) containing Pt, Pt-Ru and Pt-Sn microparticles has been investigated using cyclic voltammetry as analytical technique and 0.10m perchloric acid as supporting electrolyte.Abstract:
The electrocatalytic oxidation of methanol at a glassy carbon electrode modified by a thin film of poly(o-aminophenol) (PoAP) containing Pt, Pt-Ru and Pt-Sn microparticles has been investigated using cyclic voltammetry as analytical technique and 0.10 M perchloric acid as supporting electrolyte. It has been shown that the presence of PoAP film increases considerably the efficiency of deposited Pt microparticles toward the oxidation of methanol. The catalytic activity of Pt particles is further enhanced when Ru or specially Sn is co-deposited in the polymer film. The effects of various parameters such as the thickness of polymer film, concentration of methanol, medium temperature as well as the long term stability of modified electrodes have also been investigated.read more

Gold nanoparticles dispersed polyaniline grafted multiwall carbon nanotubes as newer electrocatalysts: Preparation and performances for methanol oxidation
TL;DR: In this article, a polyaniline (PANI) grafted multi-wall carbon nanotube (MWNT-g-PANI-Au) matrix was prepared by dispersing gold nanoparticles onto a polyANiline grafted multiline matrix through a two-step electrochemical process, where PANI chains were grafted onto amine-functionalized MWNT and the nanoparticles were dispersed into the film by electrochemical reduction of HAuCl 4.
