Abstract
For the first time, the electrodeposition of platinum from a carbon dioxide-based supercritical electrolyte with the addition of acetonitrile as a co-solvent and tetrabutylammonium tetrafluoroborate salt was studied. Dimethyl (1,5-cyclooctadiene) platinum is used as a precursor. It has been established that as a result of potentiostatic electrodeposition, not a continuous film is formed, but agglomerates of densely packed platinum nanoparticles.
