| Περιγραφή: | Three different tin deposition methods on a polycrystalline platinum electrode in sulfuric acid were studied by conventional electrochemical techniques, in order to determine and compare their influence on methanol oxidation. The deposition methods tested were spontaneous deposition, under potential deposition and cyclic under potential deposition. Tin was deposited from a solution of SnSO4 in sulfuric acid. The inhibition of the hydrogen adatom voltammetric profile on platinum by tin metal ion was used to calculate the degree of surface coverage due to tin deposition. Methanol adsorption and oxidation were compared on platinum and platinum/tin electrodes, considering the efficiency of methanol oxidation with respect to the platinum free area. |
