Binary and ternary palladium based electrocatalysts for alkaline direct glycerol fuel cell

Pt-modified Au/C catalysts for direct glycerol electro-oxidation in an alkaline medium

“…The shift was possibly caused by the reaction of glycerol on the more active Pt and also the bifunctional effect between Pt and Au in which Pt supply OH À species for the reaction on Au in the low potential region. This effect was also found on other bimetallic systems such as PdAu catalysts, whose negative shift of the onset potential was observed because of the bifunctional mechanism [2,25].…”

“…Therefore, Pt could provide the hydroxide species for removing the poisonous intermediate species from the Au surface which is called bifunctional mechanism. These promotional effects were also observed in the case of PdAu/C [25] and RuO 2 -promoted Au/C catalysts [27,28].…”

Preparation of PdAg and PdAu nanoparticle-loaded carbon black catalysts and their electrocatalytic activity for the glycerol oxidation reaction in alkaline medium

“…Pd is at least 50 times more abundant than Pt on Earth, and Pd-based alloy electrodes are highly active for the oxidation of alcohols in alkaline media. The preparation and structural analysis of Pd-based alloys, such as PdSn [8], PdNi [9,10], PdAg [10e13], and PdAu [14e16], and their activity for alcohol oxidation has been evaluated. Various synthetic approaches for metal nanoparticle catalysts, such as the hydrothermal method, solegel process, templating method, polyol synthesis, and photomediated synthesis, have been developed over the last two decades [17].…”

A Practical Approach in Glycerol Oxidation for the Development of A Glycerol Fuel Cell

“…The second peak corresponds to the glycerol oxidation which is presented in the literature by different authors [14][15][16][17][18][19][20][21][22]. In general, the catalytic activity for glycerol oxidation is observed with Pt, Cu, and Au electrodes.…”

“…The following materials have been reported: Pt [12], Pt-Ru [13], Au, Pd [14,15] and Ag [16]. In the case of gold there are several advantages over other catalyst used for glycerol oxidation, e.g.…”
