Electrochemical co-deposition of bimetallic Pt–Ru nanoclusters dispersed on poly(3,4-ethylenedioxythiophene) and electrocatalytic behavior for methanol oxidation

Nanoflowers of PdRu on PEDOT for Electrooxidation of Glycerol and Its Analysis

“…In order to examine the presence of chemical interaction between PEDOT and PdRu, IR spectra of PEDOT/C and PdRu-PEDOT/C electrodes were recorded (not shown). The spectra of both electrodes were identical with bands at 1338 cm -1 corresponding to stretching of C-C or C=C bonds of thiophene rings, and also bands at 1186, 1140 and 1085 cm -1 corresponding to C-O-C bond stretching in ethylenedioxy group [49]. It was thus inferred that chemical interaction between PdRu and PEDOT are absent.…”

“…PtPd, PtPd/Ru and PtRu particles are electrodeposited onto PANI films using cyclic voltammetry [43,47,48]. Potenstiostatic method is an alternative and easy method to deposit bimetallic particles on previously synthesized polymer matrix at a constant potential [49][50][51]. Cyclic voltammogram of PEDOT/C electrode recorded in 0.005 M PdCl 2 + 0.1 M HCl electrolyte between 0.90 and 0.10 V is shown in Fig.…”

Facile one-pot synthesis of Pd–PEDOT/graphene nanocomposites with hierarchical structure and high electrocatalytic performance for ethanol oxidation

“…[27][28][29][30][31][32][33] Nanostructured Pt and Ptbased catalysts have been dispersed on PEDOT lms or PEDOTbased composites via chemical or electrochemical methods, and all the obtained catalysts show superior electrocatalytic performance toward oxidation. [34][35][36][37] Similar to these studies, Rakesh K. Pandey and V. Lakshminarayanan synthesized the Pd-PEDOT nanocomposite lm electrochemically, involving the formation of Pd nanoparticles by the dissolution of the Pd anode and simultaneous oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) followed by deposition as a thin lm on the gold substrate. 38 Electrochemical tests demonstrate the highly enhanced electrocatalytic activity of the nanocomposite lm toward the ethanol oxidation reaction in alkaline medium although with a relatively low Pd concentration, which is attributed to the higher catalytic activity of nanosized Pd on the gold substrate and the electrically conducting path provided by the PEDOT matrix.…”

TEMPO‐Mediated Aqueous Phase Electrooxidation of Pyridyl Methanol at Palladium‐Decorated PANI on Carbon Fiber Paper Electrode

“…Among the listed polymers, PANI is significantly important owing to its low cost, high conductivity, ease of synthesis, excellent electrical properties, good environmental stability and large variety of applications such as electrochromic devices, secondary batteries, catalysis, and corrosion protection coatings. 29−31 Metal nanoparticles dispersed conducting polymer modified electrodes were reported for oxidation of organic molecules such as methanol, benzyl alcohol, formic acid, formaldehyde and toluene . Palladium (Pd) nanoparticles were reported as efficient catalysts in the oxidation of small organic molecules .…”
