These spillover processes can be influenced by impurities (pre-existing on the catalyst surface) and by the catalyst morphology that may differ as a result of the differences in catalyst manufacturing processes. This work investigates the influence of impurities present in three commercial platinum (Pt) precursors. The resulting platinum films studied here were supported on yttria-stabilised-zirconia (YSZ). It was found that the three different catalyst films contained a range of impurities (determined by ICP-OES) that appear to affect the oxygen charge transfer reaction as studied by cyclic voltammetry (CV). 2016-03-21T10:43:52Z 2016-03-21T10:43:52Z 2012-10-04 Article Solid State Ionics, vol. 225, 2012, pages 390-394 0167-2738 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41173 doi:10.1016/j.ssi.2012.06.011 10.1016/j.ssi.2012.06.011 Elsevier B.V.
