Abstract
Polyaniline-palladium composite might be proposed for the electrode material in the oxidation of aliphatic alcohols (methanol, ethanol, ethylene glycol). Prepared mixture of aniline-palladium in sulfuric acid medium (0<рН<1) is investigated by SEM, PXD and FTIR. Obtained results confirm existence of three separate regions: polydisperse palladium powder with agglomerations size of ~0.5 micron in width and ~3-7 microns in length; single palladium particles (~0.5×0.2 micron) coated mainly by polyaniline form – emeraldine; aniline balls (diameter of ~2-5 microns) with ~0.2 atomic percent of Pd in their bulk and converted at the surface to emeraldine base and emeraldine salt.
