Abstract

Graphical abstract: Highlights: Effective mediated electrosynthesis of cobalt nanoparticles was realized in solution. The cobalt anode was used as a supplier of Со 2+, anthracene was used as a mediator. The electrosynthesis was carried out in undivided cell at room temperature in DMF. The cobalt nanoparticles are oxidized by the air oxygen. Abstract: The metallic cobalt nanoparticles in the bulk solution were obtained by antracene mediated reduction of [СoCl4 ] 2− in the potentiostatic electrolysis in an undivided cell at the potential of the anthracene reduction to radical anion at room temperature in DMF/0.1 M Bu4 NCl media. [СoCl4 ] 2− ions are generated by the sacrificial cobalt anode dissolution during the electrolysis. The metal particles are oxidized upon contact with the air to form the oxidized cobalt nanoparticles with a low dispersity (20–30 nm).
