MnO2/CNT Supported Pt and PtRu Nanocatalysts for Direct Methanol Fuel Cells
TL;DR: As PtRu alloy nanoparticles were deposited on the surface of MnO2/CNTs instead of Pt, the PtRu/MnO2 /CNT catalyst shows not only excellent electro-oxidation activity to methanol with forward anodic peak current density of 901 A/gPt but also good CO oxidation ability with lower preadsorbed CO oxidation onset potential.
