Electrochemical Behavior and Electrodeposition of Nanostructured Rhodium from Low-Temperature Carbamide and Acetamide Containing Melts

Abstract

Abstract The electrochemical behavior of rhodium at low-temperature carbamide-chloride and acetamide-chloride melts was investigated. It was found that, during rhodium anodic dissolution in carbamide and acetamide containing chloride melts, mixed complexes [Rh(NH3)4Cl2]+ of quasi-octahedral symmetry D4h are produced. The composition and structure of nascent complex ions have been studied. During electrochemical reduction of [Rh(NH3)4Cl2]+ complexes, the synthesis of Rh nanoparticles, as well as Fe, Cu, and Mo nanocoatings, were realized.
