The electrocatalytic activities of PdAg nanoparticles supported on carbon black (PdAg/C) for the oxidation of propan-1-ol and glycerol in alkaline solution have been investigated. The PdAg/C catalysts with atomic ratios of Pd to Ag of 1:1 (Pd1Ag1/C) and 2:1 (Pd2Ag1/C) were prepared by a one-pot method. The characterization by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectrometry (EDX), transmission electron microscopy (TEM), and X-ray diffraction (XRD) analyses indicated a net-like structure of the PdAg alloy nanoparticles. Structural analyses further revealed no obvious enrichment of Pd or Ag on the nanoparticle surfaces. The PdAg/C catalysts exhibit significantly higher activity than Pd/C for the electrooxidation of propan-1-ol. This indicates a considerable improvement in the activity of Pd by combining with Ag, which is also favorable for substantially reducing the cost of catalyst. Pd1Ag1/C shows higher activity than Pd2Ag1/C. The PdAg/C catalysts are also superior to Pd/C in activity for the electrooxidation of glycerol, but not as effective as for propan-1-ol oxidation.
