This work focuses on systematic studies of dissolution engineering for Pt0.9M0.1/graphene (M = Au, Co, Cu, Fe, Mo, Ni, Pd, Ru, and Sn) counter electrodes (CEs). The developed nanohybrid materials exhibit higher catalytic activity and electrical conductivity compared with those of Pt/graphene CEs. The results also indicate the improved stability of the developed CEs in iodide electrolyte. Furthermore,...
Well-dispersed Pt1–xSnx alloy nanoparticles (NPs) were stabilized with RGO after a co-reduction of metal precursor ions and graphene oxide via a dry plasma reduction under an atmospheric pressure and close to room temperature. The highest electrocatalytic performance, which corresponds to the lowest charge transfer resistance of 1.12Ω, is achieved with the Pt0.9Sn0.1 NPs/RGO nanohybrid. The application...
