The study of methanol electro oxidation on the carbon nanotube modified by Ti02

In this work the surface modification and functionalization of carbon nanotubes (CNTs) were investigated. CNTs were firstly treated by acid mixture H2S04 I HN03 to introduce the carboxylic group on to the surface of (CNTs), were characterized using FT -IR techniques. The synthesized Pt/MWCNT, Pt-Ti02/MWCNT Nano composite sample were characterized through X-Ray diffraction (XRD). The electro-catalytic properties of electrodes are examined by cyclic voltammetry. In this study carbon nanotubes functionalized by platinum and titanium dioxide as a catalyst by methods of cyclic voltammetry, X-ray diffraction, scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS) was studied. Nanoparticles made of platinum and platinum Titanium dioxide ratio of atomic 1: 1 (with the same level) on the bed of carbon nanotube walls was used. The results of cyclic voltammetry proved that carbon nanotubes Multi-walled functionalized with a ratio of 1: 1 titanium dioxide electrochemical activity of platinum above (rnA Platinum titanium dioxide mg) for methanol oxidation reaction showed towards Platinum. These results are polymers (poly aniline) were tested: the role of catalytic CNT increase is much more than poly aniline, CNT catalytic role that the potential of the low and high flow makes good plays while P-Aniline can not make the CNT.
