In this study, a simple, facile and one-pot solvothermal method was developed for preparation of reduced graphene oxide (RGO) supported hollow Ag@Pt core-shell nanospheres (hAg@Pt), using ethylene glycol (EG) as a reducing agent and sodium dodecyl sulfate (SDS) as a soft template. Control experiments demonstrated that the molar ratios of the Pt-Ag precursors, the amount of SDS, the presence of RGO, and the reaction temperature were critical to the final nanocomposites. The as-prepared hAg@Pt-RGO showed the improved electrocatalytic activity and durability toward ethylene glycol oxidation, which can serve as a promising potential electrocatalyst in direct alcohol fuel cells. Experimental MaterialsChloroplatinic acid (H 2 PtCl 6 ), silver nitrate, SDS, graphite powders (8000 mesh), and EG were purchased from Aladdin

PdM (M = Pt, Co, and Ni) nanodendrites were fabricated by a co-reduction strategy. The nanodendrites displayed the enhanced catalytic activities and stabilities for methanol and ethylene glycol oxidation.
