Electrodeposition of nanostructured Pt–Pd bimetallic catalyst on polyaniline-camphorsulfonic acid/graphene nanocomposites for methanol electrooxidation

Core–shell Pd–P@Pt–Ni nanoparticles with enhanced activity and durability as anode electrocatalyst for methanol oxidation reaction

“…It is believed that the composition, shape, and structure of Pt-based nanomaterials are key factors that determine their electrocatalytic properties. [9][10][11] Until now, the introduction of less expensive metals, including Pd, 12,13 Cu, 14,15 Ni, [16][17][18][19] Ru, 20,21 Au, 22,23 to fabricate various bi-or multi-component electrocatalysts is an effective approach to not only reduce Pt loading, but also improve the activity and durability. Another promising method is to synthesize the core-shell structure by depositing Pt as thin shells on non-Pt cores.…”

Atmospheric microplasma based binary Pt3Co nanoflowers synthesis

“…Bimetallic nanoparticles are of great interest due to their wide applications in catalysis [1][2][3], sensors [4], optics [5], electronics [6], biomedicine [7], magnetics [8], etc. To date, bimetallic catalysts are typically prepared by electrodeposition [9], thermal deposition [10], the self-assembly approach [11], and galvanic replacement reaction [12]. However, these techniques are inevitably time-consuming with the introduction of environmentally hazardous species (such as oleic acid, ammonia, etc).…”

Fabricating a Self-Supported Electrode for Detecting Ammonia in Water Based on Electrodepositing Platinum-Polypyrrole on Ni Foam

“…[19][20][21] However, these nanocomposites based on conductive polymers (polypyrrole, polyaniline and polythiophene and so on) and Pt have rarely been reported for ammonia electro-oxidation and detection, although conductive polymers can reduce the consumption and prevent agglomeration of Pt, as well as can improve the electrocatalytic performance via synergistic effect. [22][23][24] Compared to polyaniline and other conductive polymers, PPy has exhibited many advantages including its low cost, neutral polymerization condition, facile synthesis and low environmental impact based on previous reports. [25][26][27][28] Therefore, fabrication of PPy/Pt nanocomposites may be a feasible strategy to enhance electrochemical activity for ammonia oxidation and realize electrochemical ammonia sensing.…”
