Effect of alkali cations on Pt based catalyst towards methanol oxidation reaction in acidic medium
Source abstract
Abstract
Abstract This communication demonstrates the effect of electrostatically adsorbed alkali cations at electrochemical interface towards methanol oxidation reaction (MOR) in acidic medium. The well-known electrostatic interaction between adsorbed OH/(OHad) species of catalyst surface and hydrated metal cations (M+(H2O)x) at the interface could be accountable for the observed different electrocatalytic activity of Pt/C and f-MWCNT/Pt-Co alloy NPs towards MOR. This cation effect has been found predominantly in weekly adsorbed ClO4− ion at Pt/C and f-MWCNT/Pt-Co alloy NPs surface than that of strongly adsorbed SO42− ion. Cyclic voltammetry results reveal that the strongly adsorbed cation at the interface shifts the oxidation potential more positively than that of weekly adsorbed cation.
