Multiwalled carbon nanotube supported Pt–Sn–M (M = Ru, Ni, and Ir) catalysts for ethanol electrooxidation

Study on ethanol electro-oxidation over a carbon-supported Pt–Cu alloy catalyst by pinhole on-line electrochemical mass spectrometry

“…[1][2][3][4] Although DEFCs are good alternative power sources, the slow kinetics of ethanol oxidation reaction (EOR) and the poor selectivity of ethanol complete oxidation to CO 2 diminish the overall performance of DEFCs, and restrain its commercialization. [5][6][7][8] Carbon-supported Pt catalyst is commonly employed as anode catalyst for ethanol oxidation in low temperature fuel cells. However, pure Pt is well known to be easily poisoned on its surface by adsorbed species such as carbon monoxide (CO) coming from the dissociative adsorption process of ethanol, hence leading to substantial losses in operation potentials.…”

Catalytic activity of platinized titanium and titanium coated with ruthenium oxide in the processes of electrooxidation of ethyl alcohol in alkaline media

“…More favorable cleavage of the C C bond under alkaline conditions is due to the fact that OH species readily accept a proton, which promotes the dehydrogenation of ethanol. 7,8 Other advantages of alkaline alcohol fuel cells include the possibility of using base metal catalysts, [9][10][11][12][13] as well as the absence of a membrane in them. 14 This not only ensures their greater variability in relation to fuel and oxidizer, but also significantly reduces their weight and size.…”
