dc.description.abstractA combinatorial sputtering system, based on magnetron enhanced plasma sputtering, was employed in the syntheses of PtxPdy thin film catalysts, and a multi-channel potentiostat allowed for high-throughput parallel screening of the deposited electrocatalysts towards the electro-oxidation of aqueous sulphur dioxide (SO2). Employing onset potential as the screening criterion, it was found that three PtxPdy bimetallic combinations exhibited satisfactory performance with the best compositions being that of Pt3Pd2 and PtPd4. Both these combinations exhibited the same lower onset potential of 0.587 ± 0.004 V, SHE compared to that of pure Pt (0.598 ± 0.011 V, SHE), and in addition contain less Pt in achieving these onset potentialsen_US
