Effect of glassy carbon properties on the electrochemical deposition of platinum nano-catalyst and its activity for methanol oxidation

Abstract: The effects of the properties of glassy carbon on the deposition of platinum particles and the electrocatalytic activity of platinum supported on glassy carbon (GC/Pt) for methanol oxidation in alkaline and acidic solutions were studied. Platinum was potentiostatically deposited on two glassy carbon samples, thermally treated at different temperatures, which were either polished or anodicaly polarised in acid (GCOX-AC/Pt) and in alkali (GCOX-AL/Pt). Anodic polarisation of glassy carbon, either in alkaline or a… Show more

“…[20][21][22][23] The large surface-to-volume ratio and active sites of these nanosized metal particles in electrocatalysis constitute part of the driving force in developing nanosized electrocatalysts. 14,24,25 The electrocatalytic properties of nanoparticle-modied electrodes depend on important factors such as the nature of substrate, the crystalline surface structure, size, and the local micro-environment of the nanoparticles. Unlike bulk lms, metal nanoparticles exhibit an unusual property of quantized double-layer charging effects.…”
