PtRh@Pt 5C/catalyst preparation for methanol electrooxidation

Bimetallic catalysts PtRh@Pt 5/C with different deposit structures were prepared by force deposition followed calcination at 400°C and characterized by cyclic voltammetry (CV) combined with XRD. The activity of the obtained catalysts was examined in methanol electrooxidation b...
