Ternary synergistic catalyst system of Pt–Cu–Mo2C with high activity and durability for alcohol oxidation

Pt/Mn3O4 cubes with high anti-poisoning ability for C1 and C2 alcohol fuel oxidation

“…This relatively low charge-transfer resistance was an indication of a high intrinsic activity and rapid catalytic kinetics for methanol oxidation in the ratedetermining step. 20 A similar set of results was also found for ethanol oxidation in which Pt-Mn 3 O 4 showed a much better catalytic performance. From the CV curves, the forward peak current density for the Pt-Mn 3 O 4 electrode at 0.76 V was determined to be about 121.7 mA cm À2 , a value about 3 times higher than the 34.4 mA cm À2 value for Pt/C at 0.71 V (Fig.…”

Surface Engineering of Flower-Like Ionic Liquid-Functionalized Graphene Anchoring Palladium Nanocrystals for a Boosted Ethanol Oxidation Reaction

“…The obvious CO oxidation peaks are observed in the first scan and disappear in the subsequent second CV scan for all the electrocatalysts. As known, the lower the potential of CO oxidation indicates the higher the antipoisoning ability of the catalyst . From Figure C and Table S4, it can be seen that the onset potential ( E co onset ) and the oxidation peak potential ( E co oxidation ) of CO oxidation for Pd/IL-RGO-2 are −0.148 and −0.092 V, which are overtly lower than the corresponding peak potentials for other catalysts.…”

“…As known, the lower the potential of CO oxidation indicates the higher the antipoisoning ability of the catalyst. 6 From Figure 6C and Table S4, it can be seen that the onset potential (E co onset ) and the oxidation peak potential (E co oxidation ) of CO oxidation for Pd/IL-RGO-2 are −0.148 and −0.092 V, which are overtly lower than the corresponding peak potentials for other catalysts. These two indicators reveal that the grafted IL on RGO and 3D flower-like structure synergistically enhance the ability of removal of poisoning CO-like intermediates.…”

“…Therefore, researching for more active and cost-effective electrocatalysts toward the anodic reaction (ethanol oxidation reaction, EOR) of DEFCs is much needed . In general, Pt-based electrocatalysts show prominent electrocatalytic performance and have been widely researched as an electrocatalyst for the EOR. − Nevertheless, the intrinsic deficiencies of Pt-based electrocatalysts, including prohibitive price, notoriously low abundance, sluggish kinetics, and easy-to-poison nature, have hindered their practical applications . As a most promising and cost-effective substitute for Pt, Pd with a similar crystal structure to Pt provides better performance and greater poisoning tolerance than Pt-based electrocatalysts for the EOR in the alkaline medium. − In addition, Pd is more nature-abundant and relatively cheaper than Pt.…”

A review of hetero-structured Ni-based active catalysts for urea electrolysis

“…[82][83][84][85][86][87] The electronic effect can be realized by introducing different components with various electronic properties such as multi-metallic components, support, and ligands. [88][89][90][91] Besides, the morphology or structure modication could induce the electronic effect. In the process of urea electrooxidation, the electronic effect plays a signicant role in the active site formation.…”
