The methanol electro-oxidation behaviors on the Pt–MoO x /C catalysts with various compositions were investigated and compared to those of Pt/C catalyst by cyclic voltammetry and chronoamperometry. The Pt–MoO x /C catalysts were prepared by depositing Pt on the MoO x /C support obtained by precipitation-reduction method in advance. The physical properties of the prepared catalysts...
A modified impregnation method was used to prepare highly dispersive carbon-supported PtRu catalyst (PtRu/C). Two modifications to the conventional impregnation method were performed: one was to precipitate the precursors ((NH 4 ) 2 PtCl 6 and Ru(OH) 3 ) on the carbon support before metal reduction; the other was to add a buffer into the synthetic solution to stabilize...
