electrocatalytic properties of platinum and it's binary alloy with vanadium in oxygen reduction reaction(orr)
نویسندگان
چکیده
the electrocatalysis of the oxygen reduction reaction (orr) on carbon supportedpt-v (1:1) catalyst in polymer electrolyte fuel cells (pefc) was investigated. atan oxygen pressure of one atm an enhanced electrocatalytic property of pt-v/ccompared with pt/c is revealed. these results indicate the occurrence of adifferent electrocatalytic mechanism for the orr on pt/c and pt-v/c. anincrease of mass transport overpotentials is observed for the pt-v/c catalyst, andthis was related to the presence of vanadium oxide. so the orr activity of pt-v/cat oxygen pressure of one atm is higher than that of pt/c.

متن کاملElectrocatalytic Reduction of Oxygen by FePt Alloy Nanoparticles
FexPt100-x nanoparticles of different compositions (x ) 63, 58, 54, 42, 15, and 0) were prepared and loaded onto a glassy carbon (GC) electrode where their catalytic activities in the electroreduction of oxygen were examined and compared. Cyclic and rotating disk voltammetric studies of the resulting FexPt100-x/GC electrodes showed that the catalytic activity for oxygen reduction exhibited a pe...
متن کاملIcosahedral platinum alloy nanocrystals with enhanced electrocatalytic activities.
This communication describes the synthesis of Pt-M (M = Au, Ni, Pd) icosahedral nanocrystals based on the gas reducing agent in liquid solution method. Both CO gas and organic surface capping agents play critical roles in stabilizing the icosahedral shape with {111} surfaces. Among the Pt-M alloy icosahedral nanocrystals generated, Pt(3)Ni had an impressive ORR specific activity of 1.83 mA/cm(2...

Stable platinum nanoparticles were prepared by the self assembly of acetylene derivatives (1-alkynes, 4-ethylphenylacetylene, and 4-tert-butylphenylacetylene) onto bare Pt colloid surfaces. Transmission electron microscopic measurements showed that the nanoparticles exhibited an average core size of 2.85 ± 0.62 nm. FTIR study showed that with the acetylene ligands adsorbed onto the Pt nanoparti...
متن کاملElectrocatalytic Oxygen Reduction Reaction
Oxygen (O2) is the most abundant element in the Earth’s crust. The oxygen reduction reaction (ORR) is also the most important reaction in life processes such as biological respiration, and in energy converting systems such as fuel cells. ORR in aqueous solutions occurs mainly by two pathways: the direct 4-electron reduction pathway from O2 to H2O, and the 2-electron reduction pathway from O2 to...
