Purification of Carbon Nanotubes and its Effect on the Properties of Carbon Nanotube/Polyaniline Nanocomposites

“…goal 13,14 . Both carbonaceous materials and conducting polymers 15,16 have been used separately as supports for catalytic systems in the design of fuel cells. Electron and proton conductivities are key words in this fi eld 17 .…”

CO electrooxidation on Pt–Ru catalysts supported on carbon nanotubes

“…Carbon-supported catalysts were prepared using lab prepared CNTs pretreated with HNO 3 2.2 M for 20 h [11]. The catalysts were synthetized by a modified polyol technique [14], employing RuCl 3 and H 2 PtCl 6 as metallic precursors and polyvynilpyrrolidone (PVP), ethylene glycol and sodium borohidride.…”

“…In this case, CO-like intermediates formed in the alcohol oxidation reaction can be adsorbed on the electrode surface lowering the cell yield [3e5]. On trying different ways to solve the problem, bi-and tri-metallic catalysts are used; they are combinations of Pt with other metals such as Ru, Ni, Co prepared as bulk alloys [6,7], deposited by different methods [8e12], dispersed onto diverse substrates [8,10,11] or supported on carbon particles [9,10].…”

“…Moreover, nanostructured carbon materials such as carbon nanotubes are being used in the preparation of supported electrodes. Recently, we have developed multiwalled carbon nanotubes, CNTs, which were used as aggregates to polyaniline films for Pt and PtRu composite electrodes for methanol oxidation [11].…”

Conducting Polymeric Nanocomposites: Preparation and Evaluation of Structural and Electromagnetic Properties

“…The considerable electrochemical and physicochemical properties result in conducting polymers having various practical applications, such as corrosion protection coatings, electrocatalysts, chemical sensors, rechargeable batteries, light-emitting diodes (LEDs), and electromagnetic interference (EMI) shielding [3][4][5][6][7][8]. Among the conducting polymers, polyaniline (PANI) has received a great deal of attention in recent years due to its easy synthesis, good environmental stability, and high electrical conductivity.…”
