Abstract
In this first demonstration of this DEMS instrument research application, the study of the methanol oxidation reaction (MOR) on HSAC supported -Pt and -PtRu catalysts is revisited. The objective of this study was to not only demonstrate the research capabilities of the DEMS instrument constructed in this thesis but to also examine the electroanalytical techniques that are commonly employed in order to study and assess the MOR reaction and electrocatalyst activities using RDE. The results presented here, however, do not simply repeat previous observations but elucidate the contrasting potential dependent conversion of the MOR to CO2 on Pt and PtRu catalysts. Three-dimensional voltammetry is furthermore applied for the first time combined with DEMS and utilised to describe the MOR, encapsulating the potential, current and time relationship of the reaction system within a single contour plot.
