Abstract

Zinc-containing composites based on polyaniline (PAni) with anilineformaldehyde polymer (AFP) were obtained by introducing ZnCl2, ZnO or zinc dust treated with ultrasound during the oxidative polymerization of aniline in the presence of AFP.The structure and morphological features of synthesized composites were studied by X-ray diffraction and electron microscopy. It is shown that the use of synthesized composites to activate the cathode in the electrohydrogenation of o-nitroaniline is accompanied by the electrochemical reduction of zinc (II) cations and the formation of micro- and nanoparticles of zinc that catalyze the process under investigation.
