The structure of the composites was studied by the methods of IR spectroscopy, X-ray diffraction and electronic microscopy. The electrocatalytic activity of the polyaniline-metal composites was investigated in a hydrogenation of crotonic acid, and it was higher for Co-containing composites. In the phase constitution of PAni+MeCl2 composites after hydrogenation were detected the crystal phases of nickel and cobalt hydroxides which define apparently their catalytic activity. ER -
