Ternary composites of multi-wall carbon nanotubes, polyaniline,and noble-metal nanoparticles for potential applications in electrocatalysis

摘要

Multi-wall carbon nanotubes were coated with a conducting polymer, polyaniline phospho-tungstate. Such composite structures have mixed electronic and proton conductivity, high surfacearea and porosity. These materials were decorated with catalytically-active noble metals – Pt,Pd, and Rh. Metal nanoparticles were uniformly distributed in the polymer matrix. Such ternarycomposites can be considered as electrode materials in sensors, electrolysers, supercapacitors, andespecially in low-temperature fuel cells with a proton-conducting polymer membrane.
