“…The combination of Pd with other metals to give either alloys or aggregates has been intensively studied over the past few years with the aim of increasing the catalyst activity and stability as well as reducing the cost of the catalyst by diluting Pd with non-noble metals. Active Pd alloys for alcohol oxidation include PdPt, 27,62,68 PdAu, 31,48,64,75 and PdNi. 40,63 Quite efficient PdPt/C electrocatalysts for the oxidation of ethylene glycol in alkaline solution have been prepared by Coutenceau et al 26 These authors have also studied the effect of the Pd:Pt ratio and of the overall metal loading on the electrode, discovering that the highest activity is attained with a 20% metal loading and a 1:1 PdPt ratio.…”

“…43,44 Zheng et al have reported the preparation of PdPt electrocatalysts by the partial spontaneous replacement of Pt on Pd film and have shown that PdPt on indium-tin oxide (ITO) is much more active for ethanol oxidation than Pd/ITO. 62 Likewise, a PdRu/Ni electrocatalyst has been reported to have a more negative onset oxidation potential for ethanol oxidation and a higher tolerance to adsorbates as compared to a PtRu/Ni electrocatalyst. 82…”

“…Several alloys with other metals were also obtained and investigated as electrocatalysts for alcohol oxidation. Active Pd alloys for alcohol oxidation were Pd-Pt [22][23][24], PdAu [25][26][27] and PdNi [28,29]. In particular, Xu et al [27] have observed that the addition of Au to Pd/C significantly promotes the catalytic activity for the electroxidation of 2propanol and also increases its stability.…”

Nanostructured (100-x)% Pd-x % Ni (x = 1, 2, 5, 10, and 20) and (90-y)%Pd-10%Ni-y%C (y = 0.5, 1, 2, 5, and 10) composite films are obtained on glassy carbon electrodes and characterized by XRD, TEM, cyclic voltammetry and chronoamperometric techniques for use as electrocatalysts towards methanol, ethanol, ethylene glycol and glycerol oxidations in 1 M KOH at 25°C. Results show that addition of Ni from 1 to 20% to the pure Pd electrode increases the electrocatalytic activity for electrooxidation of each alcohol showing maximum with 10% Ni. Further, all the Pd-Ni composite electrodes exhibit better electrocatalytic performance in the case of ethanol electrooxidation. The rate of electrooxidation of different alcohols on the active 90%Pd-10 % Ni electrode at E =-0.20 V in 1 M KOH is observed to follow the order: ethanol > methanol> ethylene glycol > glycerol. Incorporation of C from 0.5 to 10% to the active Pd-10% Ni composite improves the electrocatalytic performance of the electrode further, the magnitude of improvement being greatest with 5%C. The apparent electrocatalytic activity of the active 90%Pd-10%Ni electrode at E =-0.20 V is enhanced ~ 1.3 to 2.1 times with introduction of 5%C.
