Synergistic effect of CeO2 modified Pt/C catalysts on the alcohols oxidation

The effect of CeO2 on Pt/CeO2/CNT catalyst for CO electrooxidation

“…Ceria, with a good capacity for storing and releasing oxygen, has been reported to be used in fuel cells. Xu et al [14,15] studied the effect of adding CeO 2 to Pt/C catalysts for the electrooxidation of alcohols (methanol, ethanol, glycerol and ethylene glycol) in the alkaline solution, and found that CeO 2 significantly improved the performance for alcohol oxidation. They contributed the high activity to the synergistic effect of CeO 2 .…”

Pt and Sn Doped Sputtered CeO2 Electrodes for Fuel Cell Applications

“…High activity for the water gas shift reaction was predicated on the presence of cationic platinum [5,6] in cerium oxide. Pt-oxide materials such as Pt-RuO 2 [7] or Pt-SnO 2 [8] and Pt-CeO 2 [9][10][11][12][13] have been reported as promising anode materials for polymer membrane fuel cells (PMFC). Furthermore, the addition of Sn has an important effect on the electronic structure of Pt and its adsorption and reaction properties [3,[14][15][16][17][18][19][20].…”

Ethanol Electrooxidation on Pt with Lanthanum Oxide as Cocatalyst in a DAFC

“…Probably this result is related to the improvement of the kinetics of CO and other adspecies oxidation on Pt through a bifunctional mechanism [24] (as no alloy is formed in these materials according to previous results in [21] Figure 2 and stable current density values summarized in Table 1. The same trend previously established from the CVs is observed.…”

“…Using CeO 2 , an increment in performance was also described by Xua and coworkers [24]. They attributed the activity enhancement for alcohol electrooxidation after the addition of CeO 2 to the Pt catalysts to the bifunctional mechanism, where the formation of chemisorbed oxygen species was favoured by CeO 2 and promotes the oxidation of adsorbed carbon monoxide on the surface of Pt.…”
