Complex compounds of d- and f-elements with carboxyl- and carbonyl-containing ligands were synthesized by the electrochemical method. The influence exerted by a number of factors on the process course was studied. The dependence of the electrosynthesis parameters on the composition of the forming compounds was established. The composition of these compounds was determined. A new method for anodic synthesis of these compounds was developed.

Carbon fibers, prepared by metal-catalyzed decomposition of hydrocarbons, e.g., acetylene, benzene, and methane, present various growth models including whisker-like, branched, bi-directional, and multidirectional types of growth. The addition of additives or a second metal to the metal catalyst, the use of a support, the pretreatment of the catalyst, and the catalyst source may have considerable effects on carbon deposition. Carbon nanofibers were synthesized by the decomposition of acetylene with nanocopper catalysts to determine the effects of synthesis method on the morphologies of carbon nanofibers obtained. Copper nanoparticles catalyzed the carbon deposition of acetylene to yield regularly coiled fibers with a novel symmetric growth type, whereas ribbon-like fibers formed over nanocopper particles prepared by hydrogen-arc plasma method. The copper nanocrystals changed from irregular or spherical shape to faceted shapes after fiber growth. The regularity of the shapes of the faceted catalyst particles included in the fibers accounted for the different morphologies of the resulting products.
