Electrodeposition of platinum microparticles into polyaniline films with electrocatalytic applications

A Polyaniline-Based Selective Hydrogen Sensor

“…Garnier has reported the incorporation of both platinum and silver microparticles into poly(3-methylthiophene) [5], while Moutet has described the incorporation of palladium and rhodium into N-substituted polypyrrole films [6]. Polyaniline has also been used as a matrix for the incorporation of palladium and platinum microparticles [7,8]. These modified electrodes were shown to possess excellent stability and high catalytic activity towards the reduction of hydrogen ions in solution.…”

A Generation of Microbial Fuel Cells with Current Outputs Boosted by More Than One Order of Magnitude

“…Similar protective effects have been observed for platinum-polymer composites, used for the oxidation of methanol. [9] The performance of the novel fuel-cell anodes was tested in a model fuel-cell system (Figure 4 A) that consisted of a reactor containing an anaerobically growing suspension of Escherichia coli K12 in a standard glucose medium (55 mm glucose), and the fuel cell consisting of an anode compartment through which the bacterial medium was pumped and a cathode compartment through which the catholyte was pumped. The anode and cathode compartments were separated by a Nafion proton conducting membrane.…”

Electrooxidation of methanol on doped polypyrrole films in acidic media

“…The studies in acidic media may be compared to similar reports on other dispersed metal -polymer systems. Kost et al [24] report current densities of about 1 mA cm − 2 for 2-5 mm thick polyaniline films posited at the PPy/C electrode was done by atomic absorption spectrophotometry. A maximum current density of approximately 150 mA cm − 2 with 148.9 mg cm − 2 Pt loading in 0.5 M CH 3 OH + 0.5 M H 2 SO 4 at 25°C was used.…”
