Аннотация:Nanocomposites Pd-PPy@CNT have been synthesized via one-pot&one-step colloidal synthesis from mixed solution of inorganic salt and pyrrole monomer precursors. This method proposed in our previous papers leads to creation of nanoparticles of the inorganic component distributed inside polymer matrix. Nanocomposites Pd-PPy@CNT have been characterized as heterogeneous catalysts for reactions of direct C-C bond formation. The catalytic activity of the Pd-PPy@CNT nanocomposite was decreasing during repeated catalytic cycles with the same portion of the composite, because of Pd recrystallization inside the conducting polypyrrole matrix. The latter process occurs via specific mechanism of reaction between the solvent and the composite during C-C coupling reaction.
