Platinum Electrodeposition from a Carbon Dioxide-Based Supercritical Electrolyte

Аннотация

The electrodeposition of platinum from a carbon dioxide-based supercritical electrolyte with the addition of acetonitrile as a cosolvent and tetrabutylammonium tetrafluoroborate has been studied for the first time. Dimethyl(1,5-cyclooctadiene)platinum has been used as a precursor. It has been demonstrated that potentiostatic electrodeposition leads to the formation of agglomerates of densely packed platinum nanoparticles rather than to a continuous film.
