Electro-Catalytic Activities of Binary Nano-Composites of Pt and Nano- Carbon/Multiwall Carbon Nanotube for Methanol Electro-Oxidation
Binary nano-composites of Pt and nano-carbon (NC) and Pt and multiwalled carbon nanotube (MWCNT) have been prepared with varied compositions ranging between 20 and 80wt% Pt and investigated them as electrocatalysts for methanol oxidation. The study shows that with the increase in wt% of NC, the apparent electro-catalytic activity of the composite catalyst increases initially, reaches maximum at...
متن کاملCatalytic properties of carbon xerogels for wet oxidation of aniline
Wet air oxidation (WAO) is an old process developed in the middle of the XX century, but still the centre of very active and contemporary research especially in what concerns catalyst development. In ideal conditions soluble hydrocarbons can be oxidized in aqueous solution to carbon dioxide and water. Organic pollutants with heteroatoms are more challenging, because they require harsh condition...
متن کاملCatalytic Oxidation of Carbon Monoxide by Cobalt Oxide Catalysts Supported on Oxidized-MWCNT
Cobalt oxide catalysts supported on oxidized multi-walled carbon nanotubes (MWCNT) for the low-temperature catalytic oxidation of carbon monoxide were prepared by an impregnation-ultrasound method. These catalysts were characterized by N2 adsorption/desorption, TEM, XRD, Raman, and H2-TPR methods. The XRD and Raman results indicated that the phase of the synthesized cobalt...
متن کاملSize effect of ruthenium nanoparticles in catalytic carbon monoxide oxidation.
Carbon monoxide oxidation over ruthenium catalysts has shown an unusual catalytic behavior. Here we report a particle size effect on CO oxidation over Ru nanoparticle (NP) catalysts. Uniform Ru NPs with a tunable particle size from 2 to 6 nm were synthesized by a polyol reduction of Ru(acac)(3) precursor in the presence of poly(vinylpyrrolidone) stabilizer. The measurement of catalytic activity...
متن کاملInhibition of Catalytic Carbon Oxidation by Boron and Phosphorus
Potassium and calcium salts are well known catalysts for the reaction between carbon and O2. Current airport runway deicing agents typically use formulations containing alkali or alkaline-earth metals (see C&E News, 01/01/01, p. 30). Very effective oxidation protection of aircraft brakes is thus of great practical and fundamental interest. Phosphorus and boron compounds are known to inhibit unc...
