Abstract
The synthesis of Pt+SnO2/C electrocatalyst containing cubic Pt nanoparticles with preferential (100) orientation was performed by an alcohol-reduction process using KBr as a shape directing agent. The order of addition of the Pt and Sn precursors and KBr was crucial to obtain cubic Pt particles and a SnO2 phase with small particle sizes highly dispersed on the carbon support. Electrochemical and DEFC experiments showed that Pt+SnO2/C electrocatalyst containing Pt nanoparticles with preferential (100) orientation provided superior activity for EOR, power densities and CO2 selectivity compared to Pt+SnO2/C electrocatalyst containing Pt polycrystalline.
